armor has been said - Both In making and in repairing (all repairing including armor)
Quite likely the system that lets you smelt objects back down to their ingoty form will likely be utilized at the start whenever (if) it gets introduced unless a more specialized method is made. - as for the other two...
Well. There's uhh alt? and Alt-ctrl? or maybe that's ctrl and ctrl-alt which allow various rotations.. though they're not always perfect because the directional compass of an item isn't always upright and forward...
Also I hate games that take the use key away from use to incorporate some silly leaning/rotation key that I would just remove if possible or at least rebind. It's so absurd to have the longest string of games use E for use, but then the stray game with spin/rotate/lean goes "what's that? WASD and E and Shift and Ctrl are the same in 99% of games? F that lets make ours reversed and upside down and make you have to turn the keyboard over because unique!" It's dumb. so Dumb, so easily hate-able and dumb.
ahem.
But that's just my Opinion.
And I assume you know about the rotation buttons - and are suggesting a "auto" version, Essentially speaking - Where Alt/Ctrl "hold" and Q/F "pulse"... or rather "Hold without additional action" - while alt/ctrl would be Hold "with additional action"
Also afaik most of those are currently rebindable - I at least know I rebind action wheel from Z to one of my mouse buttons as well as character sheet, and there's still several others in controls...
