Glad you feel that way, it was one of the first few mods I made because I realised that I didn't want to run back and forth to the town to sell stuff instantly like you said, and using the shipping station and sleeping is limited to the point where it felt pointless.

I'm more than happy to make and share mods that can improve people's gameplay.

As for a mod that would let you directly sell from the inventory that is a little bit out of my capability since I have no experience with programming, but that would be a pretty handy mod.

The SellBox is by far one of the most useful mods in the workshop. It allows instant selling without having to walk all the way to the town to sell stuff. I always place mine by my major fishing spot and another right by my farm so I can sell crops and other things. Maybe someday someone will add a way to sell things right from the inventory? That'd be amazing for all the stuff that just piles up in the inventory (like petals or leaves)
