I'd love a plugin (script?) that allowed you to link by cursor position. Would this be possible?
(So, select a lever/pressure plate, when you select add link it enables the cursor and allows you to move the cursor to the thing you wish to link to, with a (flashing?) green X when you're over something that you can link to and a red otherwise (maybe yellow if you're already linked to said item?))
This could be leveraged for quickfort-like programs too.
I'd also like a plugin/script that showed you everything a particular thing was linked to. (So select a lever and it shows you the bridge, select the bridge and it shows you the lever.) Perhaps in a list with center-on-selection like the ordinary link screen?
Also, a nudge/cut/copy/paste designation tool would be awesome. (Especially if it included a mode to copy already-dug areas as "to be dug" - select the floor of the bedrooms that you already dug and copy-paste it a layer down, for example) If possible, including a way to copy buildings as "to be built" - as though you just built a new bed (or whatever) in the new location and am at the materiel selection screen. (So copy a furnished bedroom and paste it into an unfurnished bedroom and it displays the materiel selection screen for the bed, then the table, and the chair, and the chest, etc.)
