Need search and sort feature

I have been using this app primarily for taking notes for over a year. I love the simplicity of it.

Now that I have a lot notes in a book, and I cannot control the ordering of the notes (notes are ordered in the book as newest modification on top), it is very hard to find a note. So please add the following features in the future updates:
1) please add search capabilities
2) please add ability for us to organize our notes manually and ability to sort them based on created date, last modified date, alphabetical based on entry title or first line of text in an entry.
3) photo thumbnail attach to each note shows the last photo added to the note. Please allow me to specified which photo to show in the thumbnail instead.
