Suggestion: Add an option to toggle the default behavior of the X in upper right corner of the maximised sheet to minimise instead of close? Could e.g. be a Pin-button next to the X-button on each window or a checkbox in the Settings changing the behavior for all your sheets. Alternative suggestion: Add a minimise button next to the X button, much like in a normal browser window. If I have a character sheet open I know I can double click the title to minimize it to the play area (really useful). And if I click the cross in upper right corner or either minimised or maximized sheet it will instead close the character sheet. Nearly always when I just want to minimise a sheet, I end up closing it, and then I spend several seconds finding it again. It annoys me SO MUCH during game time as a GM. I have tried for a long time to teach myself to always double click the title rather than click the X, but I can't.
