1. Please add "Waiting Room" under Stored filter.

I move promo cards which I finished max level and max bonded because I want to keep them but I don't use them in my decks. I also keep cards which I idolized and threw away in the past when my deck was not big enough to keep cards that I don't use, to complete a set someday.
It's hard to manage them because they all are in deck with current Sukutomo.

2. Please change filter options into checkbox and radio.

All filter options under Account (Stored, Idolized, Max Leveled and Max Bonded) are using drop-down list. I'd like to suggest to change them into checkbox and radio buttons.

For Stored: It'll be nice if this filter option is checkbox because I can filter cards which I really have in deck and present box at once. Even for waiting room if suggestion #1 is accepted.

For others: They have only 3 options for each filter. So I can set a filter by one click. Dropdown list makes me click two times to set a filter. Option text can be very short as below.

Idolized
