1- A hotkey to toggle visibility of trees. It´s aesthetically pleasing to not hide trees and foliage generally, however sometimes you want to see what is hidden beneath and it´s annoying having to issue a pathing command or go to the options menu.
2- A hotkey to swap items in hand. I use many ranged/2hand hybrids and having to switch manually each time is a pain. Better if it works from the inventory too, since switching after a fight to start the fight with the ranged weap in hand is advantegous (otherwise you will need to reload at the start)
3- The option to autolock some items in the inventory so you cant sell them. It would be much easier to select things you wanna keep in the long run and then spam right click to sell. This way I would still have my winged mace :DD
Just giving some ideas. PEace.
