I was testing out making it load images on demand and it's been painful to implement. Got it mostly working, except right now it shows no images until you scroll at least once. If I try to manually trigger that scroll, then I've got an issue where it hasn't done layout yet, and so my code to check if images are in visible area... thinks everything is visible so it loads everything... and thus no real change. Going to see if I can fix that, but might release it as-is as a mod, as it's not too bad to scroll once after opening and it lets you filter the list before scrolling and avoid loading everything. It however requires adding new functions and can't do that until my reported bug with mod applying gets fixed.
