[BZ#701140] command to close all file comparison views
Submitted by Adam Dingle
When I'm comparing directories or in the version control view, I often open many different file comparison views to look at individual files. Sometimes I want to close them all, leaving my directory or version control comparison open. It might be nice to have a command Tabs->Close All File Comparisons that does this. If we implement this, I'd suggest the keyboard shortcut Shift+Ctrl+W by analogy with gedit's Documents->Close All.
