Memory use is up about 25%. Boo Of course that might not have anything to do with the UI changes, I don't what else they've done in this release.
The reload button up in the url bar is different enough it's throwing me off when i want to click on it. I don't even remember what the old one looked like, but it seemed like it was easier to hit for some reason. It may have just shifted around and my muscle memory needs to adapt.
Overall things look nicer and more modern than before.
