Notify should make use of the iOS 5 document two way syncing functionality.
Add the ability to limit the size of the drawable area in one page to just fit one visible page and don't allow drawing or moving outside this area.
Would be nice if you could actually login to Evernote to exchange docs
Would be nice to be able to have a calendar view of the notebook list so that Notify could more easily be used as a journal.
Would be good if the sync with evernote would actually work.
Add support for importing CSV files and also drawing and editing charts and tables inside a note.
In addition to the dashed line formatting could you add the slash ( / and \ ) shapes. This makes handwritten note look as if they were drawn with a calligraphy pen. And aids in "inking" drawing.
Add support for doing formatting inside the text editor with different fonts and colors within one text object.
Also add the ability to define a border color.
Would be interesting to add support for drawing with layers inside of Toad like you can do in a regular paint program.
When transfer of notes between the iPhone and cases should be transferred as the category.
Please add fountain pen, pencil, felt-tip, calligraphy styles for handwriting
This would be the best app for teachers creating typed notes as they lecture and present via airplay if it would update the text as you type. As it is, drawing updates as you draw but text does not.
