Looking at a new procedure for the first time can be daunting because the UI does not indicate any possible actions. It’s very clean, I appreciate it, but it doesn’t indicate the status of the system, or possible paths forward.
The Inputs / Output areas are invisible unless hovered over, or clicked, which will then show the properties
That forces the user to go read the manual, tutorials, etc… Where I think some of that friction can be removed by exposing some information in the UI.
