I usually run some cycling video in background while doing TR workouts. TrainerRoad’s window is switched to minimal mode, but I have a feeling that it unnecessary hides portion of the picture. Could you please reevaluate that usage scenario and see it there is a room for improvements?
For example, I tried to play with minimalistic layout in Paint and got the following picture. I moved some of UI elements there without sacrificing font sizes and removed chart of current interval, because it mostly duplicates digital timer. It allowed me to save noticeable portion of background picture. You might also notice that I changed trainer mode control to plain buttons. Single mouse click to switch mode is easier than selecting item in dropdown list during workout. Anyway, I’m sure you can make good layout anyway
