Problem Description

It can be difficult to understand the meaning of certain ft-selects in our settings from a distance when doing a visual scan. Part of this is due to the breadth of our settings, which is a separate problem, but having icons to reduce the cognitive effort would go a long way as well.

Proposed Solution

Implement icon capability for ft-selects, and add it to a good host of our existing ones. Placement to the right of the label (or right, for RTL languages). Ones I can think of off-hand:

• Locale Preference: language icon
• Every sorting dropdown: Dynamic descending and ascending (manual logic needed). Alternatively, all ascending for easier implementation.
• Region for Trending: globe icon
• External Link Handling: external link alt

Alternatives Considered
