Not sure what happened, but I'm not seeing the "git: <branch>" in the status area any more. Is there any option that hides that that I've accidentally tripped?
RM 3.1.1 (103.260)
[update] Thanks to support for helping me. The status bar only displays the current branch when there is a file open in the editor. Opening any source file causes the status bar to show the current git branch. Closing all tabs causes the status bar to blank out.
