I'd love to be able to control the character with only my mouse. Like with RTS games right-click to move(Maybe Ctrl-Click?).

Also some context sensitive stuff would be nice for example clicking with an artifact on a researcher to put it in(maybe that already works).
Dragging items on the floor or on specific machines would be awesome

I've tried a few things over the years regarding click-to-move.  Gets messy when there's some tiles you can be standing on as well as interacting with, and having the game know the difference was kinda tough.  There is a virtual joystick option in the settings but that's a very different feel from what you're probably looking for.  Dragging items up off the inventory bar to drop them would DEFINITELY be nice.

The artifact-research UI is in dire need an overhaul.  Originally designed to have a lot of different types of research artifacts you could collect and use in there, which is why it shows you your whole inventory on the left. 

Thanks for the feedback!
