I create a lot of screenshots during the day. Sometimes I have to edit them, sometimes not I paste them directly. That's why after making the screenshot, I copy to clipboard AND open editor. Closing the editor has a few steps:
cmd+w (save window appears)
tab (select 'no')
In other screenshot apps I use on windows a simple 'escape' closes the editor window, without asking to save.
My wish: Add a checkbox to the save window to never ask for saving, so that the save warning can be bypassed.
