The new design of the sidebar takes a lot of valuable screen estate for less urgent functions. This space could be used for recent notes, shortcuts, and notebooks. Currently the "need a little help" and Send Feedback" buttons take approximately four notebooks, shortcuts or recent notes lines. These functions can be easily found under the help menu so why have them here? I would love to loose them.
Further more the forth and back buttons at the top use very much space while they physically occupay only a small part. Why not place the username dropdown besides them?
Love to hear your thoughts,
