In an attempt to make a slightly different challenge for myself, in a new game I've decided I'm only to use the shipping bin at the end of a month. I think it'd be wonderful to see a mod that could store everything you put in the shipping bin until the nearest shipping date entered. If you set the dates 7/14/21/28 and put 50 wood in the shipping box each night from the 9th to 14th, on the night of the 14th/morning of the 15th you'd receive payment for the wood you'd shipped.
It's definitely possible to make and I actually managed to save/load items to config file. But I'm having trouble tying it to events so it would fire with enough reliability. Also, as an interesting discovery/side-note, it seems SMAPI event OnNewDay fires before the game ships items
