Some people have a very high amount of decals they may want to archive or just simply find it inconvenient to go to a individual page each time to archive something.
I suggest that to increase the speed of archiving multiple assets like decals that it is added in the drop down from the little gear button in the develop page here:
It is simply much more convenient then to go to a new page, aim your mouse at the archive button and then reload the develop page. Even if you do keep the develop page, you’re still going to new pages a lot and while minor, is inconvenient.
When selecting “Show Archived”, it could also allow archived assets to be easily restored through that same drop down list of options among Configure & Advertise.
