An idea:
We should be able to construct a Kiosk on our home streets. This would be a little 'stand' that we could place a few SDBs on. This would afford us a little permanent storage on the Home Street for items we don't want to carry around but also would like to not have to go into our house or tower to retrieve. It could also be used to sell items at particular spots on the street. I would probably have an SDB full of jars in my Kiosk, which would be located near my three firefly swarms.
The Kiosk could have places for four or so SDBs, and maybe a spot on top for a sign where a note could be pasted.
