Need scroll if multiple themes intsall

Thanks for your contribution, @Nitin shrivastava. Please, consider that the reported issue isn't a bug, but really looks more like a feature request.

It's not looking better for me.
MR reviewed and needs further work.

Can't say that those changes brings any value for the theme. Let's wait for any other maintainer's point of view.

@Paul I agree with Paul, this doesn't make any improvements but rather damages the theme. IMO we can close the ticket, it seems like a personal per-project requirement
