I was going to log as an enhancement, but given how often this has started to affect my workflow, it seems more like a bug.

The Confluence team is heavily using issue branches. This means that there are a lot of branches in the bitbucket.org/confluence repo, easily 50 today. Although we will reclaim many of the branches (after the issue is merged back), I suspect that there will continue to be a reasonable set of branches off master all the time.

When it's time to pull from master, the pull dialog takes 12-15 seconds to finish loading. There is a spinner over the remote branches combo, so I'm assuming that it's fetching them all?

Would it be possible to show only those checked-out with a browse... button when the user explicitly want's to pull from another?
