Dwarf Therapist is insanely awesome, thanks for letting me know!
Last night I played for a while and the ui and I don't completely get along, but a few cool things happened:
0) An afterthought but still cool, One of the forts I built was built into the side of a large hill and I was able to picture it using slices of the map in z-levels.
1) There were some foxes that suddenly showed up near my fort and the carpenter started making animal traps (I think someone got bit to trigger this, I don't know if it was his/her friend).
2) I found gold when I was digging out sleeping quarters and had to decide to move the quarters elsewhere (and stop digging to avoid encouraging raiders). I also accidentally dug into an underground cavern once and then cancelled the stairs and built floor tiles to try to stop them from coming into my fort. Then I tried to build stairs upwards on top of the tiles, and either you can't do it or I ran out of materials after demolishing the previous structures. Anyways, the guy that was trapped down there started starving and hunting for a small creature to eat, and I couldn't convince him to contribute to building stairs on adjacent tiles to get him back up to the main column. There was a rescue operation to save him but he wasn't very happy by the time we got to him.
The main thing here is to not beat yourself up over making a mistake and try to fix it rather than just restarting. I'll work on this new gaming philosophy.
I don't know exactly how much I'll be able to play this game (very time intensive) but it's awesome!
The lemmings just got really smart...

edit: are you allowed to build on a floor tile (you dig, then build a floor tile, then try to build on top of it)?
