Zoom and Pan chart
Users these days are very used to zooming and panning maps, in a way where panning does not reset zoom level. We find our users wanting to explore the rest of a chart after selecting the zoom level, but the current interface forces them to reset zoom, pick another region and zoom again.
A zoom-and-pan user experience would take highcharts to the next level - use the metaphor of Google Maps.

Thanks for your suggestion, but this is already supported through the panKey option. See http://api.highcharts.com/highcharts#chart.panKey. Does this work well for you?
