All reported bugs fixed and new Hand Sync feature:
On the timeline, on each slide you have a rectangle with an “s” in it. When pressed it turns red and sync is enabled. What it does is sync the slide the previous one, the one on top of it, meaning that it sketches from slide to slide without the hand going out also it synks the position with the previous one. This means that it positiones itself right after the previous slide. When the previous slide gets moved, it also updates the synced slides position.
you cannot move the synced by itself, it is locked after the “synced to” slide above it’s position. you have a switch to sync also in the slide’s control panel.
