I don't have any plans for continuing DT. I think dfhack has most of DT's functions already, or something? (I don't actually play DF)
Mostly, but disparate.
It has some of the basic functionality in manipulator. Skills, and I think something with squads. Custom professions, sorting by happiness and arrival.
It has preference counts for x preference.
It has autolabor/labor-manager which are bit similar to the labour balancer mechanism (name might be wrong) in DT, though they're dynamic.
It has script to find most common bad thought in fortress.
You can't do things like "enable armorsmithing on all dwarves who don't have a moodable skill and don't have a preference for gauntlets or highboots" or it's weaponsmithing equivalent for a common DT usage example - not in a few clicks and single filter; I think the simplest way you'd have to check the skills of each dwarf manually with manipulator and then checking the preferences for each and then enable said skill for each dwarf that matched after opening two pages about the dwarf and reading the preferences in page-long text.
Or "butcher all poults larger than 1800 cm^3" - there's autobutcher, but it doesn't check body size (no script does), only age, so it'll butcher the smaller poults which will give only nigh-useless skull. You'd have to use gui/gm-editor to navigate 3 submenus and find the body size of a given poult, then give the order for each poult.
Or "enable all medical skills on all dwarves in the fortress who are religious", if you combine hospitals and temples.
Or "assign 9 most suitable unskilled dwarves for being an axedwarf who are not in a squad into your latest squad with experienced commander".
Or "display orientation and age at once" for arranging marriages.
I think manipulator and labor-manager/autolabor and search functions for age and such are only things which do any sorting, in fact.
I surely am forgetting some things, but this is off the top of my head.
