It would be convenient to have Recently changed and / or added cards as an option to filter on in the Cards section & Deck section. This way keeping decks up to date will be much easier.

Nice idea. a "new cards" filter can really be useful (every update I have to modify all my decks and it took me an hour). also a "last modified cards" filter would be nice.

"new cards" filter + "last modified cards"
Separate them works too. ;-)
With my suggestion I intended for a filter "Recent changes" which would show them both.

Nice idea, but that would require to extend the current data model of the card database. We need to add the date of creation of the card. It's not trivial, but I like this feature.
