The current recurring task system is a bit clunky at the moment: all options have to be selected manually for each new task. It would save a lot of time to be able to set templates of pre-chosen options in the recurrence menu, and to set a default template.
Also, currently, it isn't possible to make tasks repeat with the same start/due date (just 1 week forward, etc), so I have to change these details manually on every recurrence of every task. OmniFocus is a good example of how to make recurring tasks seamless.
