An easier way to sort the dead would be REALLY useful as well, yeah.
Now we can produce slabs to memorialise a- our own dead dwarves and b- dead, named enemies including animals, I like to make proper burial plans. One way I do it is to have a series of rooms, with a stairwell down into a burial chamber from each room. The coffin is in the burial chamber, the stairway don to it is floored over so the room is permanently sealed off, and an engraved slab is erected over that floor, with the room it is in turned into a memorial room for the dorf in question. Meanwhile, memorial slabs of my enemies are erected in a social room, between the best statues and fancy cages of the best prisoners/captured beasts, with the walls engraved to show fortress history. If a particularly awesome military dorf falls after racking up a decent kill count of named enemies, I make extra slabs for his/her enemies and erect them in his/her memorial chamber.
The problem is that after say, 4 years in a reasonably fun fortress, each time I'm beseiged I have to get out pen and paper, scroll through the announcements and manually write down the names of all the dorfs lost before setting up the engraving of their slabs, to avoid duplicates. Enemy slabs are even worse, since I have to keep a permanent list of killed enemies and scroll through /u/ along the deceased section picking out the new dead enemies.
