xy2345: I have 296 games on the shelf. They are listed alphabetically. That way I scroll down till I'm in the right part of the alphabet and then I recognize the cover and voila: There it is.
I don't see how that could be improved. Having to switch between different shelves would probably take longer.
skeletonbow: One way it could be improved is to allow categorization of games into arbitrary categories. Steam and other services have such a feature and it's quite useful in organizing my game collection there, so I've got an "Active Games" category where I move games to that I'm actually playing through currently, a "Buggy Games" category where a game goes in purgatory until I can find a way to fix a problem I'm having with it, and various other categories to sort things out by FPS/RTS/RPG/etc.
Yeah, that sort of thing would be ideal
At the moment the only organisation tip I have is that I set the games I've finished to 'hidden' - don't be afraid of that option there's a 'show hidden' box at the bottom of your shelf and if you tick it they pop right back up again
OP could include games they've acquired but are really not interested in as well / instead
