Updating git plugin to switch context when switching branches

Hi all,

I am new to this community. I want to update the git plugin to solve the following issue:

Switch Context when switching branches in git: http://youtrack.jetbrains.com/issue/IDEA-69150

I have a couple of questions before I start:

a) Is the git plugin the rigt place to do it? Or is this more of a general VCS feature?

b) I would like to get this feature shipped. Do I need to contact the maintainer of the code before I do so? If yes, how do I contact the maintainer (git blame?)? Does jetbrains accept outside patches to core pieces like this?

Thanks.
