Feature Request: Pin note(s) to the top of the list

[lomapur]

First of all - great little application, thank you for working on it!

If I could suggest an enhancement:

Currently, as far as I can tell, notes in the list are sorted by recently used; what I want to propose for consideration is adding a way to "pin" a note to be always on the top of the list of notes, no matter how recently it was accessed.

My use-case is that I have 1-2 notes that are accessed not that regularly, but are important to me in some ways (to give a concrete example - I have a note called Words that contains words I want to add for my flashcard collection; I open this note pretty sporadically (when I want to add new word or when I want to add words from the list to collection), which means it regularly is buried under some random notes I make of not-so-important stuff).

Thanks for consideration. :)
