It would be nice if you could resize a character sheet and maybe other windows and lock in that size so when you open it later, it automatically resizes to the set size. Like a setting for each page. Resize and click lock. That way when I open NPC sheets or monster sheets they would be the size I need for my setup so I don't need to constantly resize the sheets when I open them. This would be extra handy if you pop out the sheet. Maybe also include the location of the sheet (within the roll 20 page).
