Thanks for the feedback!
Is the mouse wheel inverted? I honestly didn't even notice. I'll fix that.
As for the tablet, you can drop it. It's there in case the player needs an extra inventory slot for something.
I feel like restrictions where certain items simply can't be dropped hurt the immersion a bit.
It's kind of like when you can open a door but can't close it. It's a small thing, but odd nonetheless.
