When my mouse hovers over the inventory window some sort of rollover text to tell me what each slot is.
When I pick up an eqipable item and inventory window is open some indication of which slot it can be worn in or hovering over it compares it to the currently equipped item.
The ability to move tribe totem without having to place it, terraform where you really want it to be, disband, reform, place totem again.
Lastly, I know it seems to be heading into winter but it is really dark a lot of the time & I can't find any settings to turn up the brightness in video options (computer screen is already set to full) to avoid running around in basically pitch black.
Please correct me if I'm missing something really obvious.
