Multiple patch open at the same time

let s say I have a few patches I want to use during a show. What I would do is to use a simple patch with a single renderer and a switch and load all the patches I want to use. But that would often overload my machine, how can I load different patches “on wait”, best practice/special nodes ?

why not use svvvvitcher, which was build to do exacly that?

yeaaahh, why not :)
