Feature request - Decks list add columns and allow sorting

Hi,

I'd like to request the following features to be added to the list of desks (https://deckbox.org/decks/mtg).

- Add a column with the number of cards in the deck. (Use case: find decks that are incomplete or have more than 60/100 cards and need to be updated.)
- Allow sorting by columns other than Name and Last Updated. Specifically Color, Format and the requested new "Number of cards" column.

Thanks in advance
