Some of the quick fixes which IDEA suggests are never helpful to me, hence I want to disable them entirely, or alternatively lower their priority, so they will show up only in the bottom of the popup menu. In particular, I want to get rid of the "Change field type" quick fix in top position, because I always want to "Change variable type" instead.

IntelliJ tells me that I write words wrongly. That is cool. However, it does not give me any suggestions how to write them correctly, making this feature only half as useful as it could be. Can I get IntelliJ to make spelling suggestions? Working on KDE, many of my usual programs use the KDE spelling and thus are able to make suggestions...
I am using IntelliJ IDEA 2016.2.4.
Right Click on the misspelled word -> Spelling -> Typo: Change to...
Right click or press
Alt + Enter
on the misspelled word. It will display a menu like this -
On the first option, you have a sub menu which you can expand on the right but to access the spell check options, you need to select the option itself that is highlight in the screenshot above, and it will replace the context menu with another one, listing the possible spelling suggestions -
I too struggled finding this option. The menu option available (first screenshot) looks like "can be expanded only" and is not at all selectable, visibly.
I can imagine that this might not (ever) be a feature.
(I wouldn't necessarily want "other" method calls to be blue as shown in the second block; blue is just to emphasize what's different from first block.)
If there's a way to just color methods defined in the current class, please advise.
(I want this because my eyes need all the help they can get.)
No, there is no such feature in IntelliJ IDEA as of version 14.1. It can be implemented as a plugin, but I'm not aware of any such plugin.
Just documenting, as I was looking for a way to do this and I have found a way that is satisfactory enough to me.
There's a way, but it's a workaround, it will have side effects.
How:
Go to File > Settings > Inspections (Choose the Global Profile if necessary).
Type in the search: qualified.
Tick the checkbox next to "Instance method call not qualified with 'this'".
Click on Severity > Edit severities, add new entry by clicking the green + button.
Name it whatever you want.
You must put it at the bottom of the list using the arrows. If you don't, the F2 key will no longer work as you expect it as it will prioritize errors at the top of the list.
Set the Error stripe mark to #FFFFFF, or the same color as the scrollbar.
Set it bold if you wish.
If you want to set a color, you must set a background color to white (or black if you have a black interface). If you don't, the color will appear black in most conditions.
If you really want to, do the same for "Unnecessary 'this' qualifier"; there is an additional checkbox to make it only apply to methods and not fields.
Side effects:
This enables inspections, which is not desired.
Pointing the mouse cursor onto the method calls will cause a hover text to appear describing the inspection.
If your code has no errors, no warnings, and no additional informative inspections, pressing F2 will jump through these calls.
In eclipse when you hover over some erroneous text you can press F2 to focus there. What is the equivalent procedure in IntelliJ?
Whenever I put my pointer over some error the text describing it disappears.
In Eclipse it will suggest what I can do to fix something like an unhandled IO exception. I'm sure IntelliJ can also do this because some people I know who are quite skillful programmers highly recommended it to me, but- how to do this?
That is: hover over some text at is in error, see what the error is, the options to fix it, and then choose one.
If you click on the highlighted part of code, the error description will appear in a pop-up bubble as well as in statusbar.
You can then hit ALT+Enter which will offer you some options to handle the given error/warning or to disable the warning.
The actions you are looking for is called "Error Description" and "Show Intention Actions".
⌘+F1 (Ctrl+F1 on non-mac) will show the error info on based on where the caret is.
Alt+Enter will show the Intention Actions available based of the location of the caret.
In IntelliJ 12, how do I make the popup stop...popping up when I hold Ctrl while hovering over a field/method with the mouse? (see picture)
That is the "Brief Info" action (or at least that is what it is called in the Keymap reference.) To the best of my knowledge (i.e. 10+ years of daily IDEA use including all beta/EAP builds), there is no way to turn it off. Searching the settings for either "Brief Info" or "Info" does not show any pertinent setting. Likewise, searching key mappings for the same does not reveal a mapping. In fact in the keymap settings, you can only map mouse clicks, not mouse pointing (i.e. hovering). You can submit a feature request asking for a setting to disable this feature.
Just put of curiosity, why do you want to disable it? I guess I would never see a case where one would Ctrl+MousePoint unless they wanted to see this. The only case I can think of would be if you disliked it popping up when you go to Ctrl+Click on a symbol. If it is the latter, note that you can use Ctrl+B in place of Ctrl+MousePoint
Try turning off the "autopop" options under /Settings/IDE Settings/Editor/Code Completion.
I have comments that gets balloon (PEP 8: Line too long ... > 120)
I wish there was a command that will wrap the lines with few keystrokes.
Right now, even if I type Alt+Enter and press enter on Reformat file, nothing actually changes. Is there a setting or plugin I could use to accomplish the formatting easily?
Under the Edit menu, there is a Fill Paragraph option, which does what I believe you want. You can assign a key command to this in Preferences, under Appearance & Behavior -> Keymap (search for "fill").
Personally, I choose first stroke Esc, second stroke Q, because that's what I've always used in Emacs...
Firstly, reformatting won't work, not in Python at least, where whitespace is important. PyCharm's "Wrap when typing reaches right margin" option is what you're looking for. Now this will not work when you copy and paste code, but in the places where it gives you trouble, just press enter, and it will work.
To be able to auto-reformat comments (and code, for that matter) to honor a right margin after the fact, go into Project Settings under Code Style and then further under Python. Click the Wrapping and Braces tab, and check the "Ensure right margin is not exceeded" checkbox.
Now if you select a region of lines and then run the Code/Reformat Code... command, PyCharm will do its best to wrap the comments or code appropriately.
You will probably have to do some tweaking of the results to suit your stylistic taste. For example, I wish PyCharm would do aggressive filling of text in block comments, at least optionally so.
PyCharm will not reformat code such that it becomes invalid Python, so sometimes it will still leave a line longer than the margin (120 or whatever you set under Project Settings/Code Style/General).
With recent PyCharm this now is located at "Editor -> Code Style", with the checkbox named "Wrap on typing"
The Screenshot shows PyCharm version 2016.2.1 Professional.
Updated Answer:
Use "soft wraps." You can search for it in the help bar.
View > Active Editor > Use Soft Wraps
It won't work for existing text or text that's copied in, but will for any newly typed text.
