I love this idea, because I often have questions like this as I transition away from proprietary software to open source alternatives
I think listing what software equivalents it might replace listed in the card.
I do see its listed when you click on the info card in the main list, but having it be visible before that might be helpful.
I know a lot of people won’t like the little ad cards when you do click on a software to review its page, but I think the way you implementted it is good. Its not intrusive and clearly states its an ad.
Edit: removed bit about categories.
Same here, I prefer KDE, but popos has been my daily driver for a while now just for compatibility and ease of use.
Very excited for cosmic as in not a fan of gnome.
