"Automatically move items in inventory to predefined locations."
This is a feature request that I have had on our suggestions list for some time. Not sure if it will ever be added but hopefully one day it will.
"Edit: separate inquiry: How to I scale vape?"
You can change your ingame GUI settings (i.e. Large, Small, Medium, whatever in the Video Settings screen) then go into the Vape GUI and under the GUI extended options (click the plus next to GUI in the settings tab), click the "rescale" checkbox.
