Settings panel and Setup / Admin page: Checkable elements are not exposed as checkboxes to screen readers

[marvellousmachine]

In both the settings panel and Admin page there are checkable elements that aren't exposed as checkboxes to screen readers. Please, consider making all such elements exposed either via ARIA: checkbox role or converting them to native HTML checkboxes.

Examples in the Settings panel:

• ADD DECIMALS MANUALLY
• ADD UNDERSCORES TO RDS PS
• SMOOTH SIGNAL

Examples in the Admin page:

• PUBLIC TUNER (NO PASSWORD)✓
• ADMIN LOCK [ONLY ADMINS CAN TUNE]
• AUTO-SHUTDOWN

Edit: Please also make sure, all these elements get focus when using Tab / Shift+Tab to navigate across the interface.
