We currently have a button and indicator for ENV vars. Here it is with a value set:

If you set Script Runner overrides via override_tlm it will fundamentally change how your script operates. I think another icon next to the ENV vars would be useful to see at a glance whether you have any overrides active. Clicking on it would bring up the Overrides dialog like we have now. Bonus points for setting new overrides in the dialog.

Maybe one of the cog icons? Search cog here: https://pictogrammers.com/library/mdi/
