Incomprehensible UI – EveryCircuit Review

I built a simple circuit, got some traces up, but they didn't match what they should have displayed. The purpose of many UI elements is unclear. It was hard to tell if the app was doing anything in response to my input, or if it was buggy, or if I was just using it the wrong way. Couldn't find a user guide on the developers site either.
