Today I found out about default starting settings at: Settings > Tools . It is awesome and very useful . I would like to suggest a new feature I think is lacking tho: Start Paint.NET in "closed document" mode. Usually I start PdN by its shortcut and not through picture > context menu. Mostly because I always have a bunch of pictures on my desktop and it is faster to just open the program while I look for the picture I want to edit and then, drag and drop it ( totally love this feature ) . Thing is, PdN starts with a bright white blank document that usually blinds me for a second, most of time I work at night. So the natural dark background of the program itself, is preferred.
That's it. So thank you and keep the good work !
