Using Flow between my desktop and laptop has been great, but I find it difficult to transition back from the laptop to my desktop with the mouse. There seems to be a hitch where the cursor is getting stuck. I'd recommend fixing that issue, and maybe offer the opportunity to set guards at the edge of the transition to where the cursor will only flow through approved areas (example: Allow the option to set it up to where the cursor will only move to my laptop if I have it in the bottom half of that edge, anything in the top half would stop on the desktop still).
