1)Crafts:
Allow to select sub-preferences for Craftsdwarves, so a Dwarf who is a Bonecrafter won't waste time trying to make
Stone or Wooden Crafts, but will only work to make bone ones. Perhaps even allow speciallized craft workshops?
Might also be nice to allow craftsmen to have helpers.
So while the more skilled dwarf does the main work, his helper
helps him by either bringing raw material or actually helping with the craft work.
These helpers/apprentices might be assigned by the player or the be spontaneous things.
2)Fertilizing with things OTHER than potash:
Probably best for when we will have human towns, but still...
I would make it so potash will still be the best fertilizer, on a unit-for-effect basis, but you
could have dwarves dump organic refuse, preferibly before you start planting
Though to get the fertility increase you have to wait for them to rot, though.
If some day we will have animal manure, that would be an useful fertilizer too.
when Alchemy is expanded, you might put some special fertilizer, who make things grow very fast.
However, the resulting crops might not be very healthy, perhaps having effects on your dwarves other
than generic illness, especially on babies. Not much of a problem if you export this food, although a years
later you might find yourself besieged by an horde of mutants...
3)Reduce effects of size on damage:
This is currently too much. Creatures like giants can make even axe blows from strong dwarves glance
off like you were just slapping them. I think that this size = damage reduction effect should be at least
halved, and the more playable and possibly realistic thing would just be to make bigger creatures capable
of taking bigger damage. So instead of just making your axe blows glance off, that giant would be wounded
by them, but it would take MUCH more damage than to bring down an human. So, for example, after damage
that would make a dwarf or human body part red, the giant body part might just be brown or even light gray.
4)Wrestling:
Allow the use of wrestling options so you don't have to dig through a few dozen lines to select 'hand'grasps,
which are usually the most useful for breaking/strangling. Also, if it's not yet in, make it so that if you
are grappling when someone and try to move, you might choose between releasing him OR trying to drag him.
