Full Bags alarm
I move massive amounts. From crafting, to mailing, to warehousing, I always seem to tab-out while waiting for items to be retrieved from a mailbox, or for TSM warehousing to finish, or waiting to fill up my bags with crafted items to mail or store in bank/gbank. As a result, it sometimes takes me hours to get stuff where it's supposed to be... not because of the "work", but because I tabbed-out to play on another account or watch youtube videos.
It'd be nice to have an audio warning when my bags were full, or when their approaching full. Something like the sounds when a post scan is complete, but on mailing, crafting, and warehousing.
