How feature works with panels? I have created cusotm layout with panels on my dev and staging site. I added a class to panels region and exported using feature. Then I enabled it on stage site. But there was no changes on stage site. Is there anything more needed for panels update using features? Or have anyone a documentation on features with panels, panelizer and panopoly module? 

I exported Panels: mylayout (Default Config)
I noticed that, any update from feature module works only if that was created using feature module.
