Redesign notes

[Abijeet]

This issue is triaging the ideas that I have for the next version of markdown notes. I've reviewed quite a few apps (Joplin, taskwarrior etc)

Overall

• Find a better name

Technical

• Redesign and re-code using React.
• Shift to MySQLite?
• Decide the libraries to use.

Features

• Add a sync to Dropbox. (Review Joplin)
• Add an alarm, or add a new format type for alarm in Markdown itself.
• Encryption is a must.
• Have a new section entirely for notes - title and description. Similar to Joplin.
• Ability to search across notebooks.
• Support sub-notes and checklist items. In addition, in the parent note, show how many of the sub checklist items are done.
• Two types of notebooks -
  1. TODO - Daily activities, while allowing notes to be marked as completed. Pretty much the existing functionality.
  2. Documentation - Separate notebooks with tags for each notebook.
• TODO notebook to have a calendar view, similar to this - https://github.com/markdown-note/markdown-notes-doc/blob/master/docs/ui/notes.md#the-calendar
• Awesome keyboard support.
