This is a request based off of a feature in OneNote.
Often when typing we will fat finger the shift key resulting in the first couple letters of the word being capitalized rather than just the first letter.
THis plugin would be a nice QOL feature.
Example: “THe house…” → “The house…”
This might be easier if it piggybacks off of something like Espanso’s Spelling Auto-Correct System ✏️❌ | Alicia's Notes 🚀
Just an idea, I could be wrong 
but generally speaking I like cross-OS solutions to this kind of thing where possible and Espanso is great for little autocorrections like this.
