This topic seems to have been brought up before (here and here), but over a year. I just wanted to mention to The Powers That Be that interest for this feature is still extant. It doesn't look like there's a way to do it currently... if there is, please let me know, and if not please put a +1 next to it in the "To-Do" list. Thanks!
Is that intentional? I mean, isn't the Toodledo iPhone app made by Toodledo™ (the company)? If so, I assume they have the resources and technical ability to make their own app access the entirety of their own service.
In any event, this was meant as a feature request. If The Powers That Be for some reason don't ever intend on adding this feature, that's fine, but I think its a perfectly reasonable request.
