Hooves not healing is worrying, I'll look into the hoof template and see if it prohibits healing.
Pegasi have the [FLIER] tag, but it only means they'll fly somewhere they could otherwise walk. Since it's currently pretty useless, I just made them 20% faster and cooler, but I've had a fair few remarks about this causing trouble and only one or two about there being uses for it so I'll take it out. Anyone who knows enough to exploit the tag can put it back in themselves.
The plain colours are the ones available in vanilla DF's colour descriptor file, the patterns were made by me by referencing the colours in the vanilla descriptor file, and I put a fair bit of work into making them really different. The description "striped moss green and ivory" is a separate entry to "striped moss green and pearl", for example. Rather than it being done automagically by DF, it was done by me using find and replace and copy and paste. If plain colours are looking dull, I might see about adding a more extensive colour descriptor file, but I'll probably roll that back into descriptions. The problem is that I made plain colours appear about forty-odd percent of time on hair, so between that, coats and wings, you're bound to see them more than once since there's only sixty or so, but with over a thousand patterns, you'll rarely see them twice in different forts. Except for carmine and puce, that combo seems to haunt me.
I brewed a barrel of golden applejack the other day, I'm going to see if I can set [PETVALUE] at the caste level so we can't just buy golden apple ents on embark, and I'll set tissue layers there so I can covert the golden apple ents into more valuable wood. I squash the last few bugs and finish tweaking the dye plants- do we want them really rare but everywhere, or spread out throughout biomes somewhat sensibly? There's sixteen of these plants(which means roughly a gajillion conjured wood definitions), so I'm inclined towards spreading them out, then making some underground dyes or dye-mixing reactions to fill in gaps in a future update. Not that you can't just trade for seeds and grow some, obviously.
