Goals that have to be aimed, sorted by importance (1 is most important):

1. Instant change from eraser back to pen (the approx. 1sec. delay is annoying)
2. More fluent when writing
3. PDF Export
4. No problems with hands lying on screen, especially at first touch
5. More pens in quick board
6. Possibilty to organise several notebooks to a binder
7. Copying notes from one notebook to another
8. Possibility to step some steps back in a notepad (e.g. drawing some lines and deleting stuff ....) even if you have been in another one in the meantime
9. Possibilty to draw definite arrows quick

At least 1 to 4 have to be reached until i will use it.
