I agree controller support for PC would be a good thing, though I do tend to prefer keyboard and mouse for most games.
For that reason, I at least hope that Larian will at least allow us to map a key to “Walk forward” for the currently controlled character (and ideally change the behaviour of the homing key to mirror that of double-clicking a character portrait). With a bit of key remapping that would give us the ability to have something more like an over-the-shoulder view. It wouldn’t be perfect but would be so much better than now.
(I know we can click and hold to move in the direction of the mouse, but I find that unresponsive, annoying when your character or other objects are in the way of where I want to go, and clashes with the use of the mouse to interact with things. I’m glad it’s an option but desperately want to be able to map a walk forward button as well.)
