RainbowNote can hide toolbar and expand your note as "Full Screen View" mode. During full screen view mode, you can't edit the note. So you can concentrate reading it. And urls, mail address, phone numbers change as link.
To enable full screen view mode, open your note, then touch
① Return to Note Edit mode.
② Touch right and left arrows to read other notes in full screen view mode.
③ URLs, mail address, phone numbers in the note are detected and changed to live links. You can touch those link to open Safari browser (for URL), make a call (for phone numbers) or send an email (for mail address).
If you turn on the lock of a note, phone numbers, urls, mail address within a note become clickable links.
