If they monitor this thread for feedback on the PC problems, I will post a link to the issues I describe. People seem to agree.
Add to that also the need for a "add to junk" option directly from the loot pickup menu and not putting monster research items into the junk automatically. I haven't really figured out yet how or why the monster research needs to be done, but I played 26 hours before figuring out the reason why I never have the monster parts: I have simply been selling them with the autosell because someone decided to put them into the autosell category by default.
I want to turn specific attention to the proper mouse-driven camera as well (as you can see from my thread no doubt). The way you set up interaction with objects, targeting and collision-based attacks (thanks for those, btw, if only you made a proper control scheme to properly use them), the old-school "hold RMB to aim" is completely nonsensical. If you want your controls to make sense, make the camera and character movement work like in every other game with behind shoulder view (Dead Rising or Dark Souls are good examples). Mouse to aim, WASD to move, and Q & E keys for something more useful, at the player's discretion.
I have a feeling this problem is being overlooked to an extent, in light of more "hyped" issues. People are underestimating the amount of grief it causes them. Or rather the amount of comfort it would bring if it was solved.
