It takes too many clicks to search a specific note:
Search for the note of interest
Double click the note to open it
Find within note (this finally displays the search input field)
Type the word you are searching for
Instead, could you make the search input field visible by default whenever a note is open? (alternatively, allow users to configure a preference to have the search input field visible by default).
This would save many clicks for a function that is used quite often. Many notes are long and without search it's very difficult to find what we need.
