- I made the font sizes in various places to be objectively 100 times better
- I removed the incredibly stupid post status animations (I cannot believe someone decided that it was a good idea to include those in the default phpBB theme. Seriously what the fuck?)
- I removed the annoying hover effects from post and section listings
- I removed the huge-ass bold dark blue style from regular nicks and made administrators dark green instead of dark red
EDIT: There are still important issues:
- The post title is way too far right in the page title. It should be first, like "Forum software switch - Minetest Forums" instead of "Minetest Forums Lorem Ipsum Blah Blah View Topic - Forum software switch" [EDIT2: This is now fixed, mostly]
- There is no favicon
