This may be something that could be implemented for next release, if you're able to query people in adventure mode about their history or about a town, you can probably have that unit history thing implemented. If unit history gets implemented, please let's not have a wall of "Sankis Gattenbomrek engraved a masterpiece in Boatmuredered" unless we choose to - I'm fine with "In 1055 Sankis Gattenbomreck engraved 150 masterpieces in Konagusan".
I think formatting some (most?) information in DF is imperative for something like the presentation arc or whatever anyway. A lot of DF's info are borderline useless walls of text in the current implementation and would benefit greatly from some kind of different formatting (charts, tables, ASCII-icons, graphs, maybe even some complex visualization - think about how you could display wounds or the inventory with an ASCII mannequin). Even some combination rules as you mention in your post would already help (say instead of his right first toe is broken, his right second toe is broken, etc; just have "his right first, second and etc... toe are broken", or even "his entire right foot is broken").
So yeah. I guess we can expect the usual "I guess that's reasonable, though no timeline as usual".
