I use Evernote for just about everything. I recently started my masters and found that when I’m studying I constantly flip between the same notes each time. For example, if I’m going through sample problems to prepare for test I would look at notes from the last lecture, the note for reading notes, and the note that contains the answer from the back of the book. Frankly it gets old flipping around ever 30 seconds. So my proposed solution would be to have a “desktop mode” for the iPad App.
This “desktop mode” would model a physical desk. You would select the notes you want to be placed on your desktop then you would have access to features outlined below to quickly move between your notes.
