- Get rid of the hideous blue effect in the menubar and toolbar
- Slim down splitters
- Get rid of awful grippies except when collapsed (and make them
slightly less ugly in the collapsed state)
- Reduce spacing of tags in tag selector
- Tweak twisty spacing
- Get rid of stray line to the right of item pane tabs
We may still want to get rid of the menubar (#366), and we can do better
than the ugly gray backgrounds (#365), but this is a start.
I'm not sure if everything will look the same on all Windows versions,
so this will need a little testing.
