Task/To Do List Management

I’m trying to edit the content of to do list and change their due dates. The date picker field sometimes is displayed, but usually doesn’t give me the option to do anything but increase the due day by 1 day or 7 days. The phone inteface is very cumbersome so I tried on my desktop PC via Web Browser, but it’s not really any better. I’d almost say this isn’t critical, however task management is probably one of the most useful features of this device and without the ability to easily manipulate the data I don’t think I’d be able to continue using the Omi for this purpose. It is very clunky and what I’d expect from an alpha product, not something that I’ve paid for.
