Creating a themes site

Hi all!

I’ve been looking for a way to create a site that displays several themes that I’d like to introduce to my clients.

I want to have the theme’s list / gallery and the option to preview the theme. I tried using the Theme Switcher plugin – but it messes with the menus and stuff while switching between the themes.

The other option went to my mind was to create a sub-folder site for each theme, but then the main site will be heavy.

I’d appreciate any help or ideas how to get this work! Thanks in advance!
