So, evolution is one of those applications that I don't altogether like but can't work without. It's simply the only application that handles my deeply nested folder structure on the load of IMAP accounts halfway well.
Recently, however, a number of annoyances started piling up. Today I got so annoyed that I downloaded the source code and patched the stupidities away. Most importantly there are a lot less confirmation dialogs now and the folder sorter order is sane again.
Now back to Familiar infrastructure...
