The complete refusal to integrate any sort of meaningful mouse support is mind boggling.
I don't dislike the keyboard approach used right now but DF hack and it's digging templates has clearly demonstrated that folks feel the lack of good dig designation sorely.
Tangentially, I remember the MoMA devoting a large chunk of a wall in its video game exhibit to the Dwarf Fortress ASCII display. The graphical tiles look great but the sheer density of ASCII definitely had retro appeal.
