So here I just updated to CM 618, and guess what? All my User Quick Actions are gone!
How could something so simple, so basic, have been missed when the 6XX series setup / configuration code was made? It’s not like this is data from a 3rd party, this is information provided to your own product.
All that was needed was a 1-time import from the previous version.
Even better, the Quick Action storage format is completely undocumented! There’s no official way to even know where the quick actions are stored, much less if the 5XX Quick Actions can be migrated to the 6XX series.
