[Feature Request] Add archive OR multiple list support

[shtrom]

There are a number of cards that I no longer use, but want to keep if I happen to need them in the future. However, they are always displayed in the list, and make it harder to find the cards that I use more often.

It would be good to have a archive feature, where card information is retained, but they are not shown in the main list, but in a new archive list, with the ability to send cards back and forth between archive and main.

Alternatively, support for multiple lists (e.g., archive, groceries, clothes, ...), would also work, in a more flexible way.
