When using IntelliJ IDEA's Replace in Path the preview panel shows the text occurrences that will be changed as they are now. Is there any way to preview what the text will be after the change?
eg In the following I am changing "BEFORE" to "AFTER" and I would like to be able to see the line of code showing FIELD = "AFTER" before I commit to the refactor. Not a big deal for simple text but I think this is quite a shortcoming when using regular expressions and back-references to captured groups.
As of IntelliJ IDEA 2016.2, only single-file replace actions support showing replacement preview. Multi-file find & replace, as well as refactorings, only support showing the list of locations that are going to be changed, but not the state after the operation.

One feature I've found really useful in Sublime Text is the ability to fold HTML tag attributes. Is there a way to do this with VSCode that I'm missing?
I don't think there's a built-in way to do this. Also, it seems the extension API currently doesn't have a way of hiding characters, see this open feature request (except for a hack mentioned by the second comment).
Extensions also can't customize the built-in folding yet, see #3422.
To fold individual attributes just move your mouse pointer to the left of the editor, in the empty space on the right of the line numbers. Small - icons will appear. Click on the ones you want to fold items.
Keyboard shortcut is CTRL+SHIFT+].

I'm using the Community Edition of Intellij IDEA. I'm a little annoyed at how it restricts the way I use indentation in some areas. For example, it's hard to format the multi-line String below using tab key:
def text = """
This is a multi-line comment.
I want this indented.
And this too.
"""
I've been looking at the code style options but I can't figure out which one to configure.
I don't know of any configuration for multi line strings. I guess formatting the contents of Strings is in itself a bit dangerous. I expect auto format to change the format of my code, not the semantics of my code.
The following might ease your pain a bit if you find yourself doing custom formatting not supported by auto format:
Turn on Markers for turning on and off formatters. This allows you to specify comments that will define areas of your code that auto format won't touch. Look for the checkboxes in Editor -> Code Style under "Formatter Control"
If you mark multiple lines and press [TAB], IntelliJ will indent all of lines.
You can write your string without indentations and then use multi line edit (multi cursor) to indent all the lines you want at the same time.
More on that feature in the link below (and also a short video demo):

Auto-indenting in IntelliJ IDEA seems to automatically takes lines previous to the selection in to consideration. This means that if the indentation is incorrect in the part of the file you're working on (e.g., 3 or 5 spaces where there should be 4, or even worse, a mix of tabs and spaces) it's annoyingly difficult to add correctly indented code.
Both new lines I'm adding and lines I use auto-indent on because I've changed them anyway get messed up like this. Since the file I'm working on is being worked on by someone else as well on another branch, I really don't want to modify over a third of the file just to indent everything correctly, but I would still like the lines that I'm actually modifying/adding to be correct - I don't see any reason to perpetuate the error when it's not necessary.
Currently the best mechanism for fixing it I've found is to manually do the spaces on a line and go from there, but it's really quite annoying, especially since I can't use the tab key or IntelliJ will immediately move to the incorrect indentation. It's barely better than copy/pasting the text to Sublime Text, fix the indentation there and paste it back without formatting.
My apologies if this has already been asked, I've tried to search for it, but it's very hard to search for this as there's so many auto-indent questions.
IntelliJ IDEA recently added a feature (in v14 or 1v4.1 if I recall) where it will detect indentation that is different from your settings. It will honor those indentations (in order to keep the file consistent). Usually as soon as you start editing the file, you get a banner, although that can be turned off. The banner looks like this:
This allows you to modify this setting on a per file basis, or turn it off completely (i.e. the "Show Settings" option).
I suspect this feature is what is causing you the issue. I am not sure how it handles a case where a file has mixed indentation (e.g. most of the file is 4, but some sections are 3 or 5 spaces). You can try turning this feature off in Settings > Editor > Code Style > "Detect and use existing file indents for editing"
Is there a text editor that will let me shade certain code blocks with specific colors so I can easily find them later? Bookmarks are great, but I also wanted to shade with the same color all code blocks which are somehow related to each other.
and
When my current text editors autocreate curly braces or parentheses for me and I type what I want in between them, are there any that let me either jump to the end of the line to put a semicolon there, or "return" to type the next line, or do I always have to use the arrow key to get out of the curly braces? Perhaps there is a shortcut I'm missing?
I think about every code editor, including Notepad++, has bookmarks. If you're looking for a more complete IDE, it probably depends on the language you're using. For .NET languages that is Visual Studio, but you probably would have known that. For PHP, Javascript and HTML/CSS, you can use Netbeans for PHP. Netbeans is also available for Java. It is a rich editor, and I think one of the best free general purpose IDE's available.
Marking pieces of code in colors is unknown to me. I've never seen an editor that supports this. You would also need a project in which to store the start and end points of these blocks, unless you would save them as comments or so in the file itself.
Visual Studio knows regions which you can define by a start tag and an end tag. You can collapse and unfold an entire region at once, making it quite easy to navigate through larger files.
But these regions are actually part of the code file, so you cannot use this for any file, because those region markers will probably make the file invalid.
I'm still wondering why any other shortcut key would be easier or more convenient than 'arrow down'..
I'm looking for something like CSS for code. Does it exist either in an IDE, or as a plugin?
The compiler often doesn't care how many more spaces or tabs or newlines you have between tokens in your code, but people do care.
I want to specify in my "style sheet" that braces always live on a seperate line, commas are always followed by spaces, and spaces always surround operators.
Somebody else could then take my code and in their style sheet, specify that no unnecessary spaces should be visible, braces should always be on the same line as their predecessor, and functions should always be separated by 3 line breaks. But the code itself should not actually change.
Is there such a tool?
I don't think such a thing exists, the best solution is to have a custom style for local coding (most IDE's allow this) and then use a tool to reformat your source code (like Jalopy for Java) when you commit it centrally.
That way you have something that's common centrally, but can still style how you want locally.
I don't know of any tool that can arbitrarily apply a style to code without actually modifying the text itself. Since you need to edit the code, that seems impractical.
This is called code formatting and if you google "code formatter" and your language of choice you should get a list of available options.
Try some eclipse based IDE (Aptana) or eclipse itsefl and and from there you can configure how the formatting works :)
