Would it be possible to make so you can open and close expansions as well like say i want to open the mounts section but all i want to see is bfa or bc or mop so this list isnt so long to have to scroll through

This can be done by toggling the respective expansion's checkbox in the config UI, hiding all collectibles for it. Maybe some way could be added to make this easier, i.e., in the tooltip directly? Not sure if the tooltip library supports it, though.
