I recently moved to Inky due to it's vastly better writing system to Twine and needed a template much like you pointed out to fill in one or two gaps (text input, save exports). Much like Inky for writing this really elevates the experience of reading IFs that it makes you wonder why Twine templates aren't as nice as this to use.
AUTO THEMES! AUTO SAVES! GOOD PHONE LAYOUTS!
Thank you!
