Add a flip transports button to toolbar, or at least an assigned key to quick change like upgrade!
When needing to flip transports like belts, but more importantly, pipes, it is quite tedious to change a large amount if the flow in the opposite direction is desired. You have to click on each one and either hit F or manually hit the U.I button.
I propose you consider adding this functionality to the toolbar, or at the very least the ability for a hot-key so that it is easier and less tedious to change multiple pipes by being similar in nature to the pause/upgrade/unity mechanic.
Thanks!
