This issue is a result of splitting #6 into 2 separate issues:

This would be helpful for specifying how the search query is a match for a given note.

Heres's what I think this is going to require:

highlight note contents query matches

1. use div with contentEditable attribute instead of using a textarea
2. regex matches for:
   1. select the space before query match (already accomplished this today)
   2. select the space after the query match
3. replace both of those matches with the open and closing tag of an element (respectively) you can use to attach classes to so you can style them as highlights.

Highlight note title

• I think I'm going to need to switch back to using a custom notes list to make this happen. Specifically move away from using a <select> element to display the note titles and build my own. Because <option> elements cannot have styled children.
