ui requests for a “copy this” button similar to other build games

[fartron]

i’ve seen several newer players in the kitfox discord ask if there is a button that will let you place more of whatever the mouse is currently hovering over. this is apparently a highly used function in factorio and some other modern building games that they have familiarity with and it seems like something that dfhack might be able to handle.

to clarify, they want a button that “picks up” the type of building or construction they are mousing-over and immediately lets them place more of that without further menu navigation.
