TaskAgent - Plain text lists for Dropbox

TaskAgent is a simple and smart to-do list manager that can sync to Dropbox. While Dropbox syncing is optional, this allows you to edit your lists from outside the app using any text editor, and then have the changes synced back into the app.

And sharing your lists is very easy: TaskAgent supports basically every sharing feature built into iOS. Also, share your tasks with other apps by adding your own custom URL actions.

TaskAgent features:
-Interactive list interface: simple and easy to use
-Dropbox sync: your lists will always be there for you
-Dropbox editing: open the lists with any text editor and have the changes synced back to the app
-Plain text mode: simply start typing and then transform your words into tasks
-Share your lists: copy them as text, send them as an email, tweet a link, send a text message, or to other compatible apps
-Hashtag support, including #! #!! #!!! for prioritizing tasks
-Custom URL actions to share your tasks with other apps
-Task sorting options

If you upgrade to TaskAgent Premium through the one-time in-app purchase, you get the following as well:
-List folders for easy sorting
-Unlimited number of lists
-Unified Archived folder for completed lists
-URL scheme to receive data from other apps
-List and task searching
