#39 Auto fill the empty block when previewWidth is > 180

[Derek Schrock]

It seems that phpvirtualbox is set up to expect the items beside Preview are General and System. The default side of Preview (at least for the FreeBSD port is 180). This default width seems to cause everything to size/align nicely.

Setting the preview width to something larger than 180 it's possible there's a block of empty content. It would be nice if phpvirtualbox would auto fill thise content with the below setting rows (Display, Storage, Audio, etc.) makine the empty block go away and doesn't make you scroll down.

See the attached screen shot where preview width is set to 400:

var $previewWidth = 400;
