On the D&D a way to add custom resource counters with Name, Maximum and current would be nice. Maybe the possibility to toggle them visible or invisible in the sheet settings. Furthermore a plus Button to add new entrys 1 by 1, and Just as with Most other entrys in the 5e sheet a toggle for rearranging and deleting. This could be used to track NPC HP, uses of spellslots and abilities, number of a specific Item left etc
