Request SE: Show "you had this" or "you dont have this" for mounts/minions

[TW-Luna]

All we can do is hope it's a translation flub and that's not what they meant because... my god...

There is an unofficial plugin for the game that does exactly this, so that's fairly head scratching.

"Adds and indicator in item tooltips to show whether you have acquired that item.
This indicator is in the item's description near the bottom and only appears for items that are unlockable, such as orchestrion rolls, minions, etc."
