F2 works as you'd expect in v2.0. ISTR that it worked in most places in v1.0 as well.

Bonus feature for the next release of v2.0: You can now bulk-rename an album by pressing F2 when it's selected in the LHS. It changes all of the tracks within the album to have the new album name.

...and I managed to throw away about 100 lines of code when implementing it, too .
