Use consistent solid-ui  icons

Suggest using cons for the buttons to make it more international.  Could you use the same ones as the  source-pane ?

-`UI.icons.iconBase + 'noun_253504.svg', // edit button -- the pen icon

- noun_1180158.svg    --  check mark for the "Render" which I think from the user's Point of is more "Save my edits" and is when the data is saved back to the pod.
