I just got into webflow and theres a video tutorials pane on the menu bar. While I love the tutorials for brushing up, I don't think it needs to be in the editor or at least give us the option of turning it off. Otherwise I would recommend moving it to the left of the undo/redo buttons. I must have clicked that 5 times in 10 minutes trying to go between pages.
Speaking of pages. I would love the ability to drag pages I"m working on into the left bar for quick access without going in to the menu. There is so much wasted space on that side that could easily have the pages just stacked switch to.
