   See http://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/samples/highcharts/studies/direction-arrows/ for a proof of concept.

2. Provide examples in Javascript first

   All your examples are in jQuery, sometimes with footnotes about other libraries.
   Why not give out examples in JS and footnote all the libraries together?

   Javascript being native and jQuery being a wrapper like the others this would m,make much more sense.

5. Heatmap highlight row/column of a given category

   The user would click a given category name, for instance, on a list, and the heatmap would highlight the row/column that corresponds to that category. This would allow for users to look for columns/rows if interest in a faster way, especially when dealing with big datasets.

6. Add support for relative (lowercase) SVG operators in path

   This would allow SVG paths to be shorter in many cases, which would reduce data size, and make the page load faster.

   For example, SVG path for a rectangle could be
   "M400 400h32v28h-32Z"
   instead of
   "M400 400L432 400 432 428 400 428Z"
   See http://forum.highcharts.com/highmaps-usage-f14/use-of-relative-commands-in-svg-paths-for-map-t31720/

7. Arange tooltip content based on highest number

   On one of your twitter post you refer to a chart with Carlsen and annad's chess ratings over time. one ting that bugged me was that in the tool tip carlsen was always on top I think it would be an idea to arange who is on top based on who has the biggest number. downside would be if you have alot of people and the are all really close to one another in ranking so this might be a plugin or a toggleble feature.

10. Implement method for disabling legend.navigation

    We can use "legend.useHTML=true" to disable legend navigation, i.e. remove the scrolling of data serie's names in the legend box.

    The docs (http://api.highcharts.com/highcharts#legend.navigation) say "When legend.useHTML is enabled, navigation is disabled.". But disabling navigation on the chart legend should instead be a method call or a property we can set to true or false.

11. Add new series 'barrange'

    Currently the only way to create a horizontal 'columnrange' series on a datetime axis is to create an inverted graph. This makes it impossible to easily add other series like lines/splines as x/y is swapped. It is possible to simulate this with a scatter series with swapped x,y and lineWidth > 0 but this is far from ideal. Another hack is using a thick line that is broken into sub segments. But this will require you to add a new series for each colored block as a line series cannot apply different colors to segments of a line.
    It is suggested to add a new series 'barrange' that like the 'bar' series, does not require the entire graph to be inverted.

14. Datalabel position in piechart always on right side

    Hi,

    I'm having four pie chart in one container div(requirement of client)
    but due to some width issue some of the datalabel are getting cut.
    I have piechart with two datapoint, i want the datalabel to always come on the right hand side.
    pls refer : http://jsfiddle.net/46mdgk4p/2/
    in the above js fiddle firefox datalabel is coming on the left side, if by any chance i can make the same datalabel come on the right side i could have started the pie chart from extreme left of the container give me more width to play with to adjust the remaining three pie chart.

    It would be great if the smae feature will be available in the chart.

    Thanks.

15. add useExternal setting to tooltip config

    Add a new useExternal setting to the tooltip config which when set to true, would prohibit the tooltip from actually being shown in the chart, but it would still allow the tooltipRefresh event to fire. By allowing the tooltipRefresh event to still fire, an external non-highcharts tooltip can be created using the information passed along in that event. From looking into the code, this can maybe be done in the Tooltip refresh method?

    [code]
    // update the inner HTML (add the useExternal check here)
    if (text === false || tooltip.useExternal) {
    this.hide();
    } else {

            // show it
            if (tooltip.isHidden) {
                stop(label);
                label.attr('opacity', 1).show();
            }
    
            // update text
            label.attr({
                text: text
            });
    
            // set the stroke color of the box
            borderColor = options.borderColor || point.color || currentSeries.color || '#606060';
            label.attr({
                stroke: borderColor
            });
    
            tooltip.updatePosition({ plotX: x, plotY: y, negative: point.negative, ttBelow: point.ttBelow });
    
            this.isHidden = false;
        }
        fireEvent(chart, 'tooltipRefresh', {
                text: text,
                x: x + chart.plotLeft,
                y: y + chart.plotTop,
                borderColor: borderColor
            });

    Hi,

    Just like we have a plugin for grouped xAxis (commonly known as grouped Categories), it would be good if we have some something similar for grouped yAxis

17. Allow setting Min-Width specifically to Plot, thus not affected by yAxis labels length

    See Example:
    https://www.dropbox.com/s/ffraygi7gewde91/MiniIpad_ShrinkChart.PNG?dl=0

    Setting Min-Width to the whole chart is redundant, because user can always enlarge font size or text length. dynamic solution is needed.

19. Draggable guage

    Just like we have a draggable graph option, can this be done to the guage as well?
    http://www.highcharts.com/demo/gauge-solid

    I will need it to enter a value by dragging that pointer across a 180 or a 360 circle, to alter percentage like values etc.

    Thank you.

20. Inserting a tooltip option about the chart

    Some complex charts need bring some information to user.

    So, for it, to insert a button with a tooltip would be very good.
