Comment 4 for bug 133988

I think you should have the action menu always visible, and display a message if you try to click it. This seems to be a common source of confusion like bug 189450, and https://answers.edge.launchpad.net/launchpad-bazaar/+question/23892

Following on from that, in a later release maybe the dialog should say "these bugs are linked to this branch: X, Y, Z; and spec ZZ. do you want to disassociate all of them and delete the branch?"
