I LOVE DGT GTD for Android. It had everything I need for getting things done plus I can sync all of my devices to Toodledo. However, when I sync to Toodledo I lose my project hierarchy set up in DGT GDT. Instead it creates duplicate tasks on my devices making Toodledoo worthless to me. For now I will have to keep my tasks on one device until I can find another app suitable for my needs.
Please, please, please add project levels to your functionality. In doing this, I believe you will be one of (if not THE ) best GTD web apps available when considering functionality.
