fix: Change autoplay direction to select

[benjackwhite]

Problem

Since 3000 the toggle UI for autoplay misses the direction indicator.
Now that is part of a submenu its easier to simply make it a Select.

Changes

Before	After

Does this work well for both Cloud and self-hosted?

How did you test this code?
