quickly append/prepend line to note without using editor

[pbkhrv]

Proposed syntax 1:

nv feeling ok. morning was good > mood

this would show list of notes matching "mood", and when user selects one of them, extension would prepend "feeling ok. morning was good" to the note.
Using >> should append text to note (similar to shell syntax)

Proposed syntax 2:

nv mood.txt < feeling ok. morning was good

This second syntax can also be triggered by choosing "prepend text" or "append text" command from the "alt+enter" menu
