Zoom home offset if sidebar is open

[valeriodeluca]

Hi guys, this is my webmap:

www.mainjoin.eu/map/santiago/

Everything works perfectly: sidebar(v2), autopan, popup content go in sidebar panels fine.

Only a few trouble. At top right I have zoom home button.
When sidebar is close everything go fine: zoom home button center my map.
When sidebar is open the zoom home makes the same thing but the sidebar hide part of my center map.
I'd like a little right-offset on result of zoom home button when sidebar is open.
Something like:

if sidebar.close() = true
zoomhome
else
zoomhome.offset

Any advices are welcome, thanks!
