Also maybe a slight colour change for the client side toolbar icon as here its like a faint blob on the toolbar.
And no its not a custom toolbar colour either. its windows stock.

Just a comment. Almost all the regular Arduino icons have a solid white colour sideways 8 but these have a transparent effect. Maybe reverting to the standard logo ?
