add the ability to insert a custom class to data points matching specific criteria. If range is 1-9, if range is 10-19, etc.
If a data point is between X and Y integer, give it "class='low-range'" if a data point is between A and B interger, give it "class='custom-class'", etc.

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-t31720/1 voteThank you for your suggestion.

Make tooltip text selectable + suitable html generator for html tooltips + continue to show tooltip until tooltip-are-mouse-leave event
As for me tooltip functionality is quite restrictive and not very convenient for now (5.0.14).
1. I cannot select text on tooltip.
I found some examples where we just copy original tooltip, show it and then do e.preventPropagation for mouseDown, mouseup and mousemove events on tooltip area.
but maybe it can be done by some parameters?Suitable html generator for html tooltip - it is inconvenient to generate html with concatenation of string na respective params. And hard to apply event listeners on elements of html-tooltip. Maybe some helper functions to add?
continue to show tooltip until tooltip-are-mouse-leave event -…
1 voteActually it seems like you are looking for something more than a simple popover text display, especially since you mention buttons and events etc, I think it would be better for you to go with a completely custom implementation. You can hook up to point events to get started: http://jsfiddle.net/highcharts/rsvkc3x3/

add events to axis labels
there should be standard events like mouseOut, mouseOver, click , etc. available for axis labels. currently it is possible to do it through custom events plugin, but it is not compatible with latest highcharts
1 voteThe Pointer object has a nice utility that you can use to detect whether a certain class is clicked: http://jsfiddle.net/qcehvqqk/

Draw border for bar so that it doesn't increase width of bar
When a border is added to bar/column charts, the border goes X pixels around the bar. This causes the bar to overlap over the axis lines and possibly other bars. See this JSFiddle example:
http://jsfiddle.net/aaewong/6kmu11md/5/It would be nice if it could look more like this instead:

navigator axis position in xAxis array should always be at the end position or removed
Currently the navigator is positioned at number 2 point in the axis array if new axis are dynamically added otherwise it is the last element. This makes indexing int the axis array unnecessarily complicated and confusing. I want that the navigator array either be taken out of the xAxis array and have its own array or at least have a consistent position
1 voteUse the xAxis.options.className to filter out the navigator axis.

highchart - chart should be overflow = auto
Can we have any highchart functionality/feature that dashboard can automatically adjust width(HScroll bar) & height(VScroll bar) ?
Like chart should be overflow = auto (as per data)
1 voteHi, with the new axis scrollbar feature it is possible to set a fixed range on the axis, so that the scrollbar is visible for longer series: http://jsfiddle.net/highcharts/fh0ormh5/

Error bar tooltips
I would like the option to show a the numbers for a single data point and its associated margin of error (M.o.E.) bar in a single unified tooltip, as in:
[ Apples: 67.5 (M.o.E.: 63.4 - 71.6) ]
I would like this rather than having the data points and margins of error on separate tooltips or having data for all series on the same shared tooltip.
1 voteHi, you can do that with a custom pointFormatter that looks for the next series and inserts the margin of error: http://jsfiddle.net/v3yfcf2o/

support more or custom spline fit algorithms
As mention in the comments for "Fix spline plots" (http://highcharts.uservoice.com/forums/55896-general/suggestions/871839-fix-spline-plots-to-draw-a-better-generalized-line), sometimes the built in spline fit method is not acceptable. It would be great if there were other fit options built in (like D3: https://github.com/mbostock/d3/wiki/SVG-Shapes#path-data-generators) or allow custom algorithm to be plugged in.
0 votesActually there is such a method, getPointSpline. It computes the line segment from one point to the next. It takes arguments for the whole segment, the point and the index, so you can add the surrounding points to the calculation as well. See http://jsfiddle.net/highcharts/6sQjJ/.

Allow users to hit Enter to change date/time range
Currently in Highstock, if you're editing the date/time range by using the text fields, you can't hit Enter to make your changes, which is odd. Instead, you have to click the page outside of the text field. Support for hitting Enter should be added.
0 votesWe currently use the input box’s onchange event. Turns out that Chrome and Firefox already trigger the event on Enter. IE8 however fails to change the ranges on Enter.

api hook for missing data
An option for what to display in place of missing data. Currently, you can override the formatter for data labels, a simple '==null' test would work. The issue is that the formatter and display for the label is skipped on null elements in series. Could there be a second option, an incase-of-null display hook?
