I've just installed 2.1 and have been playing with it this morning, so I thought I would share my initial thoughts.
I really like the floating sub-menus on the admin side bar. I was also impressed that when I installed a mod, the install option on the Browse Packages list said "Install emulating 2.0". Nice one

You've used the same "last post" icon from fugue that I independently chose for ChalkCat! Now I
know I didn't copy my choice from 2.1 because I've only just seen it. I obviously tweaked the colour to match my theme but here's mine

I did miss the little toggle for the sidebar, but I suppose once the preference is set in look and layout, users are unlikely to need to keep toggling it, so perhaps it's no great loss... it didn't take up much room though.
As for the autosaving drafts, they're not working for me either, but I haven't checked over on the Github bug report area yet. I'm inclined to agree about the text shadows, but I guess that's something the themers can easily change. They're certainly not ugly, just subject to personal taste
