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!
