Is your feature request related to a problem? Please describe.
I've started using PicView as a way to "pin" pictures to my screen (which works better than everything else that I've tried due to its speed, minimal ui, and image features). However, the minimum window size makes it so I'm limited on how small my pinned images can be, and in some cases makes it take up a bunch of extra space.

Describe the solution you'd like
A checkbox in the settings menu to disable the window's minimum size constraints.

Describe alternatives you've considered
