That is a good idea!
For the final release of Forager I am doing with a more traditional approach to inventory:
The quickbar will stay but only for tools/weapons (pickaxe, sword, fishing rod, etc)
you should add a way to sell more than 1 item at a time
That's already in the demo! Just hold Shift to sell half the selected stack or Control to sell all of it!
When will this be added to the game? I have Alpha 5 already.
PS: This is such a fun game, I can't wait for the release! Thank you :)
