Setting: Improved Autofill Suggestions - What does it mean?

DenalB

The experimental feature is a work-in-progress change (potentially), so you may see some different results surface. It's set as an opt-in offering as it's still experimental and may not be the best at its job. Aka, the cake is still in the oven and baking type of situation. For those looking for less bleeding-edge type suggestions, off is likely the best option. If you want to give it a go, feel free. Let us know what you think.

The on setting lets you opt-in to try/test the new algorithm. Off would keep you using what you are familiar with and accustomed to.
