Couple quick things that might just be things I'm missing (I hadn't been able to play DF for over a year, and I didn't feel like spending a huge amount of time relearning everything, so I didn't reread all the technical stuff I read when I first started DFing):
Currently, Full Screen Mood doesn't work well at all with my monitor. I'm using a 16:9 27 inch HP, and all I get when I Full Screen it is a (gigantic) corner of the game. This may simply be my ignorance of a solution that already exists, but it seems like some kind of an interface problem, especially since resizing DF is rather strange, in it's current state.
And, is there any way to cause the game to automatically follow around a specific dwarf(etc)? That seems like it would be enormously helpful, in combination with Z-levels. Also, having the ability to quickly "jump ahead" to that dwarf's destination would be great (particularly when I'm waiting for a miner to mine out visible gems, so that I can give orders to mine any invisible ones behind those, without doing any unnecessary mining). Again, might just be something I'm missing.
For that matter (although I'm pretty sure it's come up before), it would be great to be able to give a dwarf orders to only mine out a particular pocket of gems/ores/whatever, either by specific type ("only mine the regular rubies in this gem pocket. If you find any star rubies, or any other types of gems, stop and let me know"), or mine out whatever's present, other than stone ("mine all the gems you find touching this gem I've clicked on, whatever their type, but don't bother mining the surrounding marble."). Ordering miners to follow veins of ore or coal would also be great. Again, I'm pretty sure this is (atleast similar to) a common request.
Possibly more On Topic: I'd love to have the ability to easily resize (via mouse) each window in the game. That would be incredibly helpful.
The "Strange Moods" find-an-item game we have now is Fun, but it would be nice if it could have it's own screen, with an easily accessible list of the items and workshop that have already been claimed, along with the hints.
I'd also love to have the ability to click on sets of dwarfs, based on their broad skills, for job lists. In other words, to be able to click on Peasants, and bring up a list of all peasants, and then give just those peasants their work orders. Scrolling through 200 dwarfs just so that I can give turn on Fishing for my 197th, 198th, and 199th migrant peasant isn't so much Fun as it is Giant Unnecessary Hassle.
Being able to *just* access all the Antmen, or all the Horses, or all the Giant Cave Swallows, to find out where a specific one is/if one of my dwarfs has wounded it (or killed it), is even more of a hassle.
This could perhaps be fixed by adding additional screens for each division, as is currently done for the nicely laid out Military screen?
Along with this, I'd really like to be able to see which beings (atleast which dwarfs) have wounds, or which are insane, but not yet insane enough to drop them from the roster, or which are holding Artifacts, instead of having to guess.
