Add "got it" tooltip for Unity log tool window

[citizenmatt]

The platform has introduced a "got it" tooltip to draw attention to a feature. It might be worth adding one to the Unity log tool window - it's very discrete right now. It's only visible when there's a connection to the editor, and doesn't even show in the button stripes otherwise. Once the protocol connection is made, the button is added to the stripe, but the tool window doesn't automatically show - it's very easy to overlook and not know it's there, missing out on log view functionality.

Or perhaps have a "got it" tooltip to point it out when you hit a breakpoint - it shows the console logs while Unity itself is unresponsive (because it's at a breakpoint)
