Idea for a priority plugin:
Right click on a any todo or note gives access to menu item “Priority” with the following entries:
Higher
Lower
No priority
(A)
(B)
(C)
(D)
(E)
What happens when user chose an item:
A-E : (A-E) is inserted in the subject line. Example: Remember milk is changed to (A) Remember milk
Higher: (B) is changed to (A) etc. If the todo is already at (A) nothing happens. If todo does not have a priority yet (A) is inserted.
Lower: (A) is changed to (B) etc. If the todo is already at (E) nothing happens. If todo does not have a priority yet (E) is inserted.
No priority: Any given priority is removed from the subject.
