Need more tools to remove, hide or edit everything that shows up after "When equipped:".
In default trinkets slot it's not possible to hide anything and for other custom slots your only option is to hide everything, even the equippable slot.

Proposed solution:
Adding settings on data/trinkets/tags/[group]/[slot].json that allows to show equippable slots and effects for every item tagged in that slot.
Like "show_equippable_slot": true/false and "show_trinket_effect": true/false

You can modify default trinket slots, there is nothing special about them. You are right that showing equippability and attributes is tied to the same value though.

Maybe I'm doing something wrong about the default slots then. Still, separation between the two would be good, especially if a trinket has multiple different slots avaible or has a ton of attributes
