Retrieving a single attachment
If you’re only getting one item from the group, it’s because your inventory is [near] full.
However, that’s not your thread. Your thread is a suggestion which means it will most likely be moved to the Suggestion section shortly.
You can suggest it by posting there, however I highly suggest NOT crossposting/multiposting because the Dev’s (namely Mr. Moderator) will move this thread.
I don’t know if the Dev’s plan on doing anything like this but I wouldn’t hold my breath. It would incentivize using your Mail as a storage system, which is what they intended it not to be.
Ah lol. Yes I like storage. I’m a horder! I keep buying additional bank slots and just keep filling them up!
Thanks for your reply!
