UI is unresponsive with lots of repo tabs

When SourceTree has multiple repos open as tabs, it can be a struggle to interact with the Commit button. I suspect this is because SourceTree will "wake up" and start polling the repos when you switch back to the tool. What this means though is that the time I switch to Sourcetree to do some work is the time that Sourcetree starts doing background work, and I am blocked.

Ideally I should be able to stage files and hit the commit button and have SourceTree add these actions to a queue so they can be completed when whatever background tasks are being run complete. This saves me from waiting for SourceTree to finish, or to compete with background tasks to interact with the UI.
