We have had complaints from lecturers that the new 'record' and 'stop' buttons are similar in appearance. It would be useful to have more contrasting colours, particularly in a busy classroom environment with lots of distractions.

Additionally, when a recording is started the record button is removed from the screen and the stop button is moved to exactly the same location. This has led to unintended double presses of stop/record in teaching situations when the UI is laggy.
