may i suggest a hemingway mode?

Hemingway Mode is a writing technique or software feature designed to separate the creative drafting process from the editing process by preventing the writer from modifying existing text. this artificial constraint helps writers focus on creative flow and producing raw first drafts, though some find the inability to correct typos in real-time frustrating.

though in the case on harper, harper will not highlight the incorrect spellings and grammars until the writer ends a sentence (by inputting a "."?) or a paragraph or when the writer manually activates spelling and grammar check.

the reason for this feature is to help the writer to concentrate on the content of the composition and prevent the nuances of distracting highlighted incorrect spellings and grammar by harper.

it may even improve harper responsiveness, resource usage and performance because it may reduce the frequency of spell and grammar checks.
