How to display current SVN branch in Intellij IDEA title?

It's not supported yet, please vote for this open request to get this feature implemented sooner.

I simply hit the 'Update Project (Ctrl+T)' to identify branch. In a 'Use branch' field it will show current branch.

But of course it's not as convinient as to have some status bar for branch or something like this. Sometimes I forget to switch between branches and I think that if there will be such bar then it may solve this trouble.
