If it were possible to have plugins add text to folders (and files?) in the sidebar, I could see some great uses out of it. For example, it would be really helpful to be able to see the current git branch I'm working on, or which files have been modified since the last checkin.
eg (imagine this is the sidebar):
- jsdocs.py (*)
- Base File.sublime-settings
This shows that the JSDocs folder is on the develop branch and that I have local modifications to jsdocs.py
