I tested the collections like Dr. Hippo suggested. And while this mostly achieves what I want. Would it be possible to allow for changing the size of the grid in a collection?
Itch by default uses 3 column wide grid for games and 4 column wide grid for collections.
I tried changing that using the CSS Editor, but when I do so, it breaks on mobile as itch uses 2 wide columns there. Is there any workaround for that? And if not, can it be added as an option?
