An old addon I used to have would set the character when you click the addons button instead of defaulting to ALL. Would this be something you could add? Thanks

Character-specific addon selections by default? Would be nice
I remember that addon too - blizzard UI still sucks for addon management

It appears that Blizzard have fixed the issues with the Dragonflight code which prevented this option from working so it has returned.

10.0.35.alpha.1 - 1st February 2023

• The 'Show character addons' ('System') option has returned. If checked, the game addon list will show character addons by default.
