It's great that you guys are addressing this, but I'd like to reaffirm the original request. It would be great to be able to disable the tooltips. They are quite an annoyance when I'm trying to collaborate with coworkers that are viewing my screen. Yes, there is a presentation mode, but I want the ability to be able to quickly make edits and zoom in/out when needed.
I think it would be more tolerable if the tooltips helped the overall experience, but it only ever says "Double click to edit."
