Currently the autocomplete feature is capped at a relatively small number of characters, which often cuts off mid-sentence and forces users to manually finish their thought. This limitation interrupts workflow and reduces the value of the autocomplete engine for longer text passages (e.g. drafting emails, articles, or code comments).

Desired Behavior

• Support suggestions up to some fixed of characters, but configurable.
• Allow users to choose a max-length setting globally (to not configure in every document).
• Ensure performance remains smooth even at higher limits.
• It could be like copilot, you can see the full completion if you need.
