Sync to localStorage

[tuhuynh27]

Your notes will not be saved until you login. I respect your privacy, I just can't find a better way to save your data if you don't login 😉

It can be implemented to be able to save temporary text to localStorage (without login), every 5 seconds, will it be more convenient? 😃

Yeah it can be done easily, I originally implemented it to save on every key press 😆 but then removed the whole thing in favor of Firebase login and multi-device syncing, there's no other reason for it. We can add it back.
