Longtime lurker, but I made an account explicitly to ask for the requests.
Please add [REACTION_CLASS:IS_STONE] to all of the stonecrafter reactions. I got tired of my dwarfs running to the other side of the fortress to grab wood planks and end up contaminating my orders of stone doors or what not with the occasional wooden one, I've fixed this for myself for my games, but it also gets annoying to reapply it with every update.
Also please add at least one blocking square to the footprint of all magma workshops. The magma metallurgist, crucible, weaponry, armory and some others all have a nice hole to the magma that occasionally a dwarf can fall into or a damn magma creature can crawl out of.
Also please bring back standardized gem shapes (using as short of a name as possible)
All in all, though, good stuff. Please keep doing what you're doing.
