BTW push button doesn't work though.

Thanks for the contribution! And sorry for the late replay 😬 I'm sorprised that people actually use it 😀
Unfrotunately @amitamb I tried this, but it has a problem when you have 2 panels and push both of them, it push the main container twice. The solution it should be, to check if there is a panel already open when you push the main container and do nothing if there is one opened. (I'm just thinking out loud 😛 )
I'll take a look when I have some free time.
