rework materials from the ground up

[Frank_Stein]

Make it possible to use welding tools on glass shards to create glass panels, it's a minor thing yes but it completely ruins getting off the diner z-level without mining access since you can't repair it yourself.

Welding ores could be like ghetto smelting in that in melts the material into a hot puddle on the floor that cools into a sheet, faster if you dump water on it.
