Problem
See the attached screenshot, only the left most action "Stop" has a tooltip, but the other three don't.
I have no idea what the second-from-the-left action does.
Without tooltips, there's no way to tell what some of these cute little icons mean :'(

Scope

• Update all the action items across the tabs to ensure they have tooltips

Tooltips

• Stop
• History
• Edit
• Add favourite/Remove favourite
