Can't believe no one praised this yet. The new commit dialog in #957 is simply astounding, guys. Pretty and functional, the kind of thing I expect from IDEA (not to mention that it finally fixes a dimension bug I filed long ago).
Now the only caveat left is to add keybord shortcuts for all the checkboxes in the dialog (and one more to focus the comment area). A simple task, I suppose. Way to go, folks!
