I've got a few suggestions about the interface
*In descriptions of skeletons, body parts, etc. of named creatures it would be nice if it stated what kind of creature the character was (ie. Dwarf, Goblin, Human, Elf, some kind of pet, etc) instead of just "This is a <NAME>'s skeleton"
*It would be great if we had the option to sort the Pen/Pasture menu by creature type, by grazers vs. non grazers, and by strays vs. pets vs. untamed
*Names could stand to be more consistent. The different screens seems to switch between the translated and untranslated versions of characters' names without rhyme or reason
*Any screen where you select between multiple creatures (ie. pasture menu, military menu, kill menu, animal stocks, et cetera) that doesn't have it already would be improved by the option to view the selected creature's description (and return to the previous menu and selection by pressing escape and/or zoom to the currently highlighted creature.
*It would be nice if we could resize activity zones
*It would be great if we could switch back and forth between animal stocks and animal units
*Any place where you select from a list would be greatly improved if we could select by text string (stocks, pastures, military, construction, etc.)
*Many things currently selectable by text string are hampered by the search only checking against the creature's untranslated name rather than titles, descriptors, or translated name.
*It would be nice if we could prioritize constructions like we can with designations
*It would be nice if Units->Other could be sorted/grouped by type (ie. Wild Animal, Diplomat, Guest (possibly further sorted by reason for visiting), Uninvited Guest, Merchant, etc.)
*A lot of things in the adventurer journal run off the side of the screen. They might benefit from being right justified.
*Constructions would benefit from an button to simply use the same material for the whole construction (rather than having to press enter for each square)
*It would be nice to be able to set up constructed staircases all at once instead of having to wait for a level to be built before setting out the next.
*It would be great to be able to switch freely between the (k), (t), (q), and (v) menus without having to exit and reselect the square.
*It would be nice to view unit description and stats from the petition screen
*It would be nice if we toggle the kill menu (s-a-k) to not show caged creatures, guests, or merchants.
*It would be nice to have the option to access the (k), (t), (q), and possibly (v) readouts without pausing.
*It would be nice to view stocks by material
*It would be nice if descriptions of things told you their color.
