The new export wizard feels like a regression.
You system used to save some default values. Now having to click through the wizard every time is a hassle. It doesn't support system copy and paste, either.
Editing existing tasks doesn't seem to work well, either. I can't seem to modify the existing query that the task is based on. I use the same sort of template all the time, but change details in the query -- aggregating on an order ID, for instance. The order IDs change, but the aggregation remains the same. So, I have to rebuild the export every time.
All in all, a regression, IMO.
