you could instead of the shrinking itembar that is buggy becouse you get removed items when you sell one. have a bar that Always is at 20 and items pop up when you get one instead of it schrinking when you get 19
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)
That's already in the demo! Just hold Shift to sell half the selected stack or Control to sell all of it!
