There is one quite important thing missing from the game.
If you have split networks it is really difficult to see the status of each one especially with pipes. Once there are two or more pipes together it only displays one reading but does not say for which pipe it belongs (See Also). There needs to be a way to easily see what each network is doing.
Also, when you click on a pipe the title of the popup is “Pipe Network” which we already know. A bit more meaningful information would help.
