When editing markdown files in intellij, I am not seeing the visual guide for columns at 80 and 120.
In Preferences | Editor | Code Style, I have Visual Guides: 80,120.
Is there another setting that I need to enable?
I'm using Intellij Ultimate 2018.1.5.
I saw a thread elsewhere where someone was having a similar problem, and it turned out their color scheme meant they couldn't see the visual guide:
Please check whether Setting | Editor | Colors & Fonts | General | Right margin is a color that's visible against your editor background.

How can I increase the number of spaces of a single tab indent?
I noticed that in another project a tab corresponds to four white spaces, but in the current one it is only two.
It is a simple question, but I have not found an answer and it would save me a lot of time.
It's configurable in the code style settings: Settings (Preferences on macOS) | Editor | Code Style | Java | Tabs and Indents | Tab size.
Some projects may override it via EditorConfig. If you don't want it, disable Settings (Preferences on macOS) | Editor | Code Style | Enable EditorConfig support.
How to show blue dot icons when files were modified with Git in PhpStorm IDE like this picture?
Please help me setup for this in PhpStorm IDE. Thank you so much.
PhpStorm (and other IDEA-based IDEs) does not have such dots. Instead the file name color is used to specify the VCS file status.
Default colors and their meaning can be seen here: https://www.jetbrains.com/help/phpstorm/project-tool-window.html#file_status_highlight
You can see and change those colors at Settings (Preferences on macOS) | Version Control | File Status Colors
The IDE can mark the actual folders with colors as well. There is an option for that (see https://stackoverflow.com/a/30915650/783119 for details). These days it's located at Settings (Preferences on macOS) | Version Control | Confirmation screen and is called Highlight directories that contain modified files in the Project tree.
The colors that will be used here (so you can change them if needed): Have changed descendants and Have immediate changed children.
How can I change colors in resulted diagram generated by Intellij IDEA UML plugin?
On image below you can see that actual colors are not readable. Diagram was generated from database.
I am not asking about how to change whole color scheme. I am satisfied with my color scheme. This is the only thing which I need to change.
UPDATE: #Andrey suggested how to change color of text from dark green to something else (Settings (Preferences on macOS) | Editor | Color Scheme | General | Text | Default text). But I noticed that this dramatically changes other parts of my code editor. I am using light mode in IDE and I think that more useful will be to change background color from almost black to something lighter. So the question was specified more closely to "How to change background color in diagram generated by Intellij IDEA UML plugin?"
I have found it. If you are interested, this is where you can change background color in diagram generated by Intellij IDEA UML plugin:
Settings | Editor | Color Scheme | Diagrams | Node background
Settings | Editor | Color Scheme | Diagrams | Node header
I don't understand this markers (between line numbers and collapse/expand markers). What words I should to google to find a documentation about it? Thanks.
updated: It is not a Gutter
It comes from Version Control plugin, the definition of colors you can find here: File | Settings | Color scheme | VCS.
That area is called the Gutter in IntelliJ speak, so you can search the settings for that term. It's typically used to show file differences when a file is under VCS control (git, svn, etc) but can also have other usages.
I just downloaded the new version of WebStorm -- 2016.3.2. For some reason all my HTML tags are highlighted grey.
Does anybody know how to fix this? I've tried looking around in the settings and I posted on the forums too.
Edit The problem persists even with all the html styling disabled.
Edit 2 Even with highlighting set to none it still happens
Add new Schema in Preferences | Editor | Colors & Fonts | HTML by hitting Save As...
And now you can uncheck Background configuration for removing it or change the color.
