I am spending hours on zoom calls and start to use the annotate feature alot even if I keep thinking they could be better (i.e. switching to mute while in draw mode). My 2 questions: - is it thought to be an independent draw tool floating on the screen compared to the built in tools we see? - anychance to combine it with a screenmirror on a tablet with pen (or am I wrongly understanding the benefits)? Thanks
