Hey! Almost three years later, I finally decided to try using the panel tool in Clip Studio Paint Pro . Here's a silly, fast comic I made. 

I just drew some random panels and filled them up with whatever. When in doubt, draw a cat!

Anyway, I'm trying the panel tool on the next batch of Foxes & Boxes comics I'm about to draw. It took some tweaking to get my scans to line up withe grid the right way. Now, I can use Snap to Grid to draw the panels more or less to what I drew on my graph paper.
