Like some other people here I only found out about Toodledo through your app in Preware.
I was looking for a good todo online service that I can use on my Pre. I didn't like RTM, this looks like the perfect deal. Now I only need Outlook sync, but I saw this should be possible as well.
I have actually moved on from Toodledo to another task list service that better fits my working style. I am planning to develop a Palm Pre app to sync with that service when they have an API available. At this time I have no plans expand TaskAdder, but could perhaps be persuaded to work on something if there is enough interest.
Is there any chance that you could open source the project if you are no longer going to be updating it? I am a big Toodledo user and thinking of moving to the Pre once they open up the Tasks & Calendar APIs a bit more. This is something I would love to work on in the near future.
