hi! @raszpl
so no language required and back to satus.storage.remove, which can be done for all settings.
#1685 (highlight: "once a user resets any feature, then we can delete the value from storage.") 🎉

(except for those 5 switches in the player section that are inverted as of now #2042 (comment),
which satus already inverts in the active features list)

[raszpl]

yep
