Feature request: Focus modes about folio

[JohnJohn1809]

Sometimes working on longer texts can be a bit distracting. Some editors use focus modes (examples from ThiefMD below) to help users focus on what's most important at the moment. I'd love it if Folio had a mode to focus on the paragraph you're currently editing.

Paragraph focus:

Sentence focus:

I also miss this feature. I came to make her request here on github. I hope it is implemented, Folio is very good, I am impressed with it. I've been using Apostrophe for a while and this was the main drawback I had when using Folio.

This doesn't seem something that I'd add, though if someone wants to submit a PR for it I wouldn't be against it.

Apostrophe's focus mode is simpler than ThiefMD's, with only sentence focus available, but it's well done and when combined with typewriter scrolling that's more than good enough.
