I play Grim Dawn using a controller. It works great, and I love it. However, there is one instance where I have to use my mouse and keyboard. (otherwise the process is painfully slow)
When transferring items to my stash, there is no “Shift Click” using the controller. Having this would allow me, and possibly others, to use the controller 100% of the time. 
Without it, moving all those items and components into the stash becomes very difficult.
It seems you can hold the L3 button to attack without moving… so there is some “Shift Click” functionality there. Having it for the menus, as well, would be amazing.
Though I’m probably the only one interested in something like this, I remain hopeful!
