Feature: Single left click behavior to full screen+shortcut

[Aamir3d]

Current Diffusion Toolkit behavior on single click does

1. Select thumbnail > Preview window with prompt info
2. Double Click Thumbnail to view full screen.

Once in the full screen, you cannot double click (expected behavior) to exit, but need to press ESC to exit.

Alternative (IMO better behavior), allow the first two, Additionally

1. Single Click Preview to enter full screen, (and keep the functionality to scroll wheel as normal (zoom in and out), Click and drag to pan, and
2. Single click to exit fullscreen

Alternative shortcut - ENTER to enter fullscreen like Irfanview behavior (already happening in the Thumbnail), but not when clicked on the main preview window. Alternative shortcut - + and - keys to zoom in and out, and arrow keys to scroll view.

hi, i think single click would create unintentional issues since our general usage on windows is single click to select something and double click to activate any kind of option, whether full screen or whatever. single clicks can cause NSFW issues in SFW situations when not intended. rest of the suggestions are ok.

But whatever the dev decides. cheers
