I got the update for the launcher but didn’t notice the change. My vault cache now matches the purchases I made from the store without having to go back to the website. I think this is great!
There is a Caveat here however! As the store grows to hundreds or even thousands of items, it could be valuable to add a way to hide items in the vault that aren’t currently being accessed. The result being, that when I start the launcher I see all the items in my vault that I’ve left visible. And then a button can list all the items that I’ve set to hidden.
