So I am creating the most amazing server with some never before seen features and I was wondering if you could add dimensional Id questing support. Its super crucial to my ideals. It would need to have the following support. Dimensional Quests, Biome Specific Quests, Globally Available Quests and Time Based Quests. Also if you could add NPC support with sub Support for MCA that would be SWEET!

One last thing, if you could make the quest limit and insane number like 999999999999999 that would be awesome than I never have to worry about hitting the cap.

I like the idea of this, but you can work with the dimensional quests being the location function.
the others will need to be added to be practical.

NPC and MCA Support, do you mean speaking to them or trading with them as part of your quest?

I am thinking maybe allow none disintegrating or removable npcs that give quests. Like World Of Warcraft Style

The cap should already be removed with the new saving, loading and networking for 1.9+

Dimensional location tasks will hopefully be coming with 5.4. See #421.
