I think it would be a good idea to have an extra option to sort notes and notebooks by priority or by your choice of the desired order of the notes and notebooks. This would be useful because the order of the notes and notebooks will not change no matter what unless you change your desired order of the notes and notebooks or change the priority setting on them (if you decide to add a priority setting over the desired order of the user). This will add a new noting style for people who like it this way. An example of a priority setting would be similar to tags, but you could only have three options (depending on the number of options/priorities the Evernote team decides to program in the software) and a maximum of 1 option to assign to the notes and notebooks. The options could be A, B and C (with A being the highest priority at the top of the list of notes and notebooks and C being the lowest). The options could also be 1, 2 and 3. This is different from the other system where the user chooses the desired order because the desired order system could just be dragging notes and notebooks to their desired order between the top and bottom of the list of notes and notebooks without assigning a priority to notes and notebooks.
