It needs a name because you can do stuff on a Kit level. And that functionality makes sense, don’t throw out the baby with the bathwater.
The pattern menu:
10.5.2 CLEAR • KIT DATA
Clears the active pattern’s kit. All sequencer data will remain unchanged.
10.5.3 SAVE TO PROJ • KIT DATA
Saves the active pattern’s kit to the +Drive. (Excluding the sequencer data.)
10.5.4 RELOAD FROM PROJ • KIT DATA
Reloads the active pattern’s kit from the +Drive. (Keeps your sequence data.
And there’s probably more functionality on the kit level coming. Copy/Paste Kit and Import/Export Kit are my best guesses.
Being pissed that a Kit is locked into a pattern is another story, I get that some like the other way where kits are on a project level and you link one or many patterns to a single kit.
