[h2oearth]

It will be great of we add something like this to the Pi extension. I added to my env and love it :-)

Oh this is nice, the active indicator plus mode icon is the right amount of status. Thank you for the clean diff and the screenshot. This is a real feature, so I would love it as a PR so you get the commit and the credit. If you would rather not, say the word and I will wire it in with attribution. Leaving open until it lands.
