The new status-icons and their colors are a real improvement over the Alpha! I tried to hover them on the start page of the plainkit-panel but I don't get a tooltip with their title attribute and this is because they are set to pointer-events: none. You could prevent this with a wrapper like described here.
I know this is a minor one but it could be frustrating for new panel-user on their first visit when they try to guess the meaning of these icons.
Additionally the title could be changed from "Public" to "Public (Disabled)" in this case.
