I'm using a dark theme in IntelliJ 14, the problem is that I have difficulties in distinguish the active tab, because its header's background is not different than the other tabs I have opened (or it is, but very little). I looked all over the place for a method to change the color of the active tab header's background, no luck so far. Please help?
Although, if you are still using IntelliJ 14:
Under
File \ Settings \ Appearance & Behavior \ File Colors
,turn off "Use in Editor Tabs", as test tabs background are dark-green by default, which is similar to the dark-grey non-selected tabs.
After that, optionally you can set the colors under:
File \ Settings \ Editor \ Colors & Fonts \ File Status
and change the Foreground color of "Modified" status.
Now it will highlight the modified files (in version control).
