I suggest adding a feature that would allow users to store their CFTs in an organized and easily accessible manner. This feature could be in the form of custom collections or family, in which the user could group his CFTs according to his own criteria.
They could also add descriptions or notes for each collection.

I would also like to have the possibility to sort our CFTs by date of acquisition, rarity, id, collections, etc.

And why not add the possibility to leave a small message/description for each of our CFTs
