If I were able to script I would for sure work on it, because it's almost one year I DM a lot in that side of the server and I've noticed myself what is missing when a DM is not there.
I. Some countryside areas, on the model of what has been recently done in Hazlan and on the way to Krezk. More for some herb, wood, and simple animal hunting, than for real adventuring. In this way adding the chance to craft things as part of automatic mini-quest (like those of crafting wheels, barrles, etc in Vallaki). That could be paid, turned in, to the several NPCs in the Bazaar, the, let's say, economic hub of the town. Providing leather for books to the several bookshop is another possibility. Added to this, maybe, as an idea, some generic spawn of thugs/brigands of those of the town, which would be spread in a larger area and thus avoiding people "stealing" it to each others. I'd say 3-4 maps would not be too hard to add.
II. I have used myself sometimes the idea of the "escaped experiment" on the crossroad to University. Mages are common in Dementlieu. Some laboratory idea on the mood of the Scrags liar would fit a lot in Dementlieu.
III. War zone. Something on the idea of Invidians, with Falkovnian mercenaries and skirmishers, if some more of 3-4 maps were added in the country. A sort of dangerous zone where war may break out at any moment.
IV. There are some activities in town which, in time, I've tried to use to give IC jobs. The Theatre of the Cathedral needs a key for the backroom. The Golden Fig and the Croissant Bleu may have the same system of Igor in the Broken Bell, that is that of the waiter/waitress buying undercost things and then RPing the role (this would need less and less a DM). The Broken Spire and the Bullseye could be helped by an accessible area to possible waitress/waiters too.
V. This is a bit more problematic. I've employed some 5 people as Gendarmes in time, as I've tried to mark a difference between those who are citizens (locals), those of more recent citizenship (many PCs) and all the others, occasional visitors of the town. S ome form of OCR or grade of criminality which could be applied to PCs without needing a DM supervision would help dynamics.
VI. A road by the bay with some villas which could be used to host NPCs or someone who is employed for them.
VII. I'd love, but that is very personal, the other sides of University being opened, such as the History or Religion quarters.
VIII. Some form of "illusion" dungeon, maybe hosted within the halls of an asylum, modelled maybe on the Lich Tower scheme.
[EDIT] IX. A sort of Drain, freaks friendly, to be built in the sewers.
