I would like to see the available daily/weekly quests on the map. Is that something you consider of adding?
If so, could you add the 'basic' support for it, I would be able to help contributing the data through PRs.

The main thing it's missing is some way to know which daily/weekly is up on a given day, for ones that rotate. It's possible that a way to check for that is available in the assorted quest APIs, but I would need to go investigate.
