In the left (control/dashboard) panel,
you need to click OFF one selection before clicking ON another selection.
If only one is available at a time, these should be radio buttons.
If more than one is available at a time, they should be selection boxes.
The ON/OFF sliders are not appropriate
In the time slider for some entries, it seems necessary to click to change the time.
This should be a rollover, without clicking required, since there are only discrete time points available.
