FR: Filters for music and cards

[outloudvi]

Here's a feature request about filters to select certain music or cards.

Ideas I have thought of:

• Cards
  • Team (HA, PP, PM, M4, R, LL or others (a.k.a. Mitchie))
  • ⭐ count / Rarity
  • Attribute
  • or keyword match on any field
• Musics
  • Type (Original, Cover, Remix, Game etc.)
  • Team (HA, PP, PM, M4, R, LL or others)
  • Have any difficulty varient falling in a certain level range?
  • Chart spec (TEC/EFT/NTS/SCR/DNG/NTS), if possible?
  • or keyword match on any field

I'd like to help if it's not already worked on yet.

The base structure on the code for filtering is done, but untested. You can check on JSON API the available data which you can use and then make your filters. So, go ahead if you want
