Familiar's Special Abilities

Am I missing something or there’s no way to use familiars’ special abilities (for example, the Dragon Breath ability, added to a custom pseudodragon familiar) while controlling them? I checked out the context menu, the spellbook, the feat list – nothing there.

methinks you’d have to set them up as context-menu items, similar to eg. class or race abilities. And/or as feats that can be dragged onto the hotbar. Then, it is possible to set up a GUI-element to invoke a targeting cursor …

custom stuff for custom stuff, though
