Rob opened a UI Review tracker bug for Anjuta the other day and asked me on Monday if I could help out. I had a quick look this morning and filed about eight new bugs in total. By lunchtime, Johannes Schmid has already been fixing most of them. So, if you see any HIG violations in Anjuta, especially now that it is going to become an official part of the GNOME platform, please add them to the depends of the tracker bug!
ps. The new library.gnome.org makes browsing the HIG really nice, but looking at the screenshots is a bit like looking through a short history of the early days of GTK+ 2. Maybe I’ll find some time to update them all to look a little more consistent and modern!
