It would be cool if the way the SDB acts when being used in a tower to sell things could be changed thus:
- Hang on wall and put in an item, then set price (existing today)
- When the SDB runs out of the item, the item image changes to a faded version with "out of stock" text over it. The pricing information remains.
- The owner restocks by dropping the same item on the SDB again, the image changes back to normal.
- The pricing information entered initially is returned without having to be set by the owner again.
- When the SDB is showing the "out of stock" message and the owner drops a different item on it, it acts like an empty SDB (eg. item gets placed and no pricing data is retained until set by the owner again).
This would solve for a couple of annoyances I have run into when selling things in my tower. Namely trying to remember which items were where and how much I had them listed at.
