Hey,
I'd like to be able to style the navigator better, by changing the size and color of the handles and by making the color of the navigator change between selected and un-selected areas.
This is what I'd like to end up with:
1) Custom navigator background color (supported)
2) Custom selected chart area color (supported)
3) Custom unselected chart area color (not supported)
4) Custom, bigger navigator handles, preferably icons (not supported)
This is a fairly small thing to add I suppose, but would greatly benefit the appearence of Highstock charts that use a navigator. Currently the handles look horrible pretty much regardless of what you do, as only the background/border color can be changed. I also think that bigger handles would be "more inviting" on touch input devices to users who are new to the functionality.
EDIT: Also it would be nice if the cursor changed according to the functionality of the navigator, so when on hovering over the handle you'd get resize-cursor, when hovering over the middle of the navigator you'd get grab-cursor to indicate pan-functionality, and when hovering above the unselected area of the navigator chart you'd get default cursor.
This is a very small detail that ruins the appearance of an otherwise well stylized chart, at least for me.
Is there any way to achieve this result now? Best I could come up with is: http://jsfiddle.net/0k0e40sr/1/
