Is there any possibility that a general Autocorrect feature could be added to the existing Spell Checker?
I generally write in a stream of consciousness and don’t pay any attention to capitals or even spelling. If the first letter in a sentence and proper nouns could be capitalized, that alone would be massively helpful. But fixing general spelling errors - a la Word or SwiftKey - would take it to another level.
Here’s a list of open source Spell Check tools, some of which appear to include such a function.

NordSpell seems to be the standard one used by Openoffice, Firefox and more), but SymSpell sounds like an extremely impressive alternative.
