The filtered decks get used quite a lot with tag heavy premade decks . But they can get confusing so I keep a sticky note of what each one is for . It would be better if we could add temporary label for the filtered deck so it stays as a filtered deck but not just a number next to it , it also has a name to easily identify the purpose of that deck below is an example concept
Is it not possible to “swipe your finger from right to left over” the decks to get the option to rename them?
Yes but that changes that deck to a actual deck not a filtered one
With filters you can rebuild and empty as needed so the cards never become part of that deck instead of their original one.
Are you sure? The name doesn’t matter so the deck should remain a filtered deck and its name should remain blue.
No, it does not.
Correct.
