Adjusting height of view based on the features

[tchannagiri]

Hi again devs,

I am trying to adjust the size of the view programmatically based on the size of the features present so that there is not too much excess. One way I have found is to look at 'genomeView.view.tracks[2].displays[0].layoutFeatures' to find the min/max y values and adjust the height accordingly. I considered making the resize code in the 'onchange' callback of 'genomeView' but it seems that 'onchange' is called when the change is initiated not when it is compete. So my question is:

1. Is there any way to trigger a callback when the layout or drawing is completed?
2. Is there already an autoheight feature hidden somewhere in JBrowse?
3. Will this require me to create a custom plugin to extend LinearBasicDisplay or LinearGenomeView, etc.?

Thanks!

Best,
TJ
