This addon will just warn you in chat if you have a finished or unfinished daily quest in the zone you are jumping out of. If you get the alert, you may reconsider and cancel the jump if needed.

It's not perfect, but it helped with my problem of constantly leaving places with some daily quest steps still incomplete.

It only works if you use house/guild/group/friend jumps (I use Faster Travel addon for that).
It's no good if you use wayshrines, or instantenous teleports.
