I have a couple ideas for you coders:
1. Rain barrels. (workshop/building)Build these with one empty barrel and maybe a log for rain catchers. These, of course, must be outside. In biomes with rain, they'd fill with rain as ponds do. This would be a nice watersource for an early fort, working like designated zones and wells do. They'd have clean water to prevent absolute dehydration, and for reactions. You could use a bucket to retrieve the captured water.
2. Water barrels (workshop/building)These, of course, are related to the above. All you need is one empty barrel to build. While you'd need a bucket brigade to fill them and keep them filled, they'd make a nice handy water source for hospitals, et cetera, without the need to dig a well nearby or channel water.
Hmm, you could also do this with booze.
Dwarven
water alcohol cooler! They already gather at the barrels to drink straight from them. Nice way to distribute alcohol without dealing with stockpile management.
3. Museum (room and items)This one's for the mods with display cases.
First, I'd like not only cases, but pedestals (just a block will do), too. Both are built especially to display artifacts and other interesting things. The difference is the cases provide theft deterrence, and the pedestals can't. Cases would be good for the small things, pedestals for the large and heavy stuff that no one tries to steal.
Either on build or post-build query, have filter option to see artifacts only, so you can put up your
useless priceless items up for display. (That is, if this isn't in the display case code already. Haven't tried them yet.)
On query, you can set up a Museum room, which would work just the same as a Sculpture Garden. Hopefully the parties thrown there won't break stuff.
