I HATE the new <select> you are forcing us to use to select the span of a chart.
The space saved by taking away the span buttons (1D 5D 1M...) is not improved by putting the span options into a dropdown.Fewer clicks is better - the new select requires a second click. Less mouse movement is better (I am mouse challenged) and the select forces me to move my mouse a second time, after activating the select, to then have to move my mouse again to the option.
