I'm sorry if this question has been answered before but googling and searching the forum I couldn't find the answer.
I have a project with several branches and I want to be able to switch between them. So I have each branch checked out in a different directory. I open up redmine, open the first directory. Open a second directory, and when rubymine asks" New projects can either be opened in a new window or replace the project in the existing window.
How would you like to open the project?" I ask for a new window. I now have two instances of rubymine running. It would help enormously if i could colour them differently - I really don't care how - just some visual cue to let me know which branch I'm on. I guess this is easy to do, but cannot see how.
