frankly, im not sure what all spells are included in nameplate auras, so i dont want to delete all spells then readd them case by case, could you include a checklist of spells to show/hide, or maybe a blacklist to manually remove specific spells?

unstable affliction is useless information for anyone that isnt a warlofk, and if youre a warlock, you need to have specific addons or weakauras to show your own unstable afflictions, not other warlocks as well, so this addon displaying something like UA is quite bothersome

Sorry, "blacklist for whitelist" seems to be strange.
You can set NAuras to show only your UA in UA spell options.
