Repository registry disappeared, can't bring back
Created originally on Bitbucket by Anonymous
At the upper right corner of the repository registry, the patch queue, and the output log are two tiny buttons with no tooltips to indicate what they do. One is an "X", which closes the widget. To the left of that is a button that looks like two overlapped windows. I clicked that, and now my repository registry is gone. The menu command //View | Show Repository Registry// won't bring it back.
It occurred in TortoiseHg 2.2.0. Upgrading to TortoiseHg 2.2.1 didn't fix it.
