i'm sure you're going to get a lot of influx of users and questions with this new huge ukraine bundle. I've not really used itch.io much before. But i've installed the app, have all the games in my library. But cannot find anyway to filter in the same sort of manner as when looking at the Itch 'marketplace'.
ie I can select tags and genres etc. Once a game is in your library there doesn't appear to be a way of looking things up in the same sort of way. It has a filter but from what I can tell that is just filtering by the name of a game. which isn't at all useful in this context.
having 1000 games now in my library. I have no idea which games i will want to try and explore because I can't filter them down to the genres that I enjoy. It doesn't even give you a 'count' of games/tools/assets/books/physical games either.
