5. Make pie slices selectable through data labels

   In pie charts slices with very small percentage (e.g. 0.01%) currently aren't selectable. This could be fixed by handling click events on data labels.

6. colorByPoint for scatter plot

   Add colorByPoint option to the scatter plot. This would allow coding a third dimension by color or intensity in a standard scatter plot.

7. Provide printable container

   Provide a container such that if a user wanted to print/export the container, the container and all contents would be printed/exported. Highcharts provides this support on a per chart basis, but we need the printing/exporting on larger scale.

16. Export images using canvg

    With very few codeline changes in export.js you could convert the svg into a canvas using http://code.google.com/p/canvg/

    Then send the canvas.toDataURL to the server and let it reply a base64_decode of it, or alternatively use Downloadify to eliminate any server interaction altogether.
    This way highcharts doesn't require any conversion library like batik and can be used everywhere (without internet access for export.highcharts.com)

    Your Highcharts library rocks btw!

18. add an option to open the export menu on 'mouseover' instead of 'click'

    Currently, the exporting modules export button opens the export menu when the user clicks the button. It would be nice if there was an option to have this menu open on mouseover instead.
