The updated icons and text help a lot! The url bar is a little tricky to read for developers that may frequently refer to it. Both versions look great! Personally I like the contrast of the previous version because I run a ton of add-ons, but the overall flow looks great on both. From a design standpoint, I LOVE the maximum graphic visibility of this new one. Still my absolute favorite theme :D
The newest version makes the URL bar and icons completely hidden & unusable since there is no transparency to offset the colors/icons/fonts. Keep having to roll back to the 'previous version' (which was 5 stars and perfect!) then turn OFF the updates for this theme so it doesn't update to the newer unusable version. My favorite theme by far!
