I've never made use of VCS in intJ -- I use git but it seemed simpler to me when I first started using the IDE to just keep doing what I was doing manually and ignore the occasional popup. I'm still fine like that.
Gutter colors are something I've paid occasional attention to, but not enough that them being there or not is something I think about, until right now, when suddenly I want to be able to find recently changed lines.
Which is when I noticed there are no gutter colors at all. I read in a few bug reports this might be just because of a particular color scheme, but when I switch to standard Darcula nothing changes.
Then looking for the gutter color configuration I noticed these are actually tied to the VCS interface. Do I need to configure that somehow in order for this to work? And tangentially, can I do it in a "read-only" way? I do little scripting things with git and would just prefer that nothing complicate that (currently, `.git` is there but read-only for the intJ process).
