[PD] help needed: "conditional" help patches

[Christof Ressi]

Ok, I have a come up with the following solution: I moved the 
multichannel section into a dedicated patch and open it with [;pd open 
<name> <dir> 1( when the user clicks a bang button in the main help 
patch. It's not perfect, but kind of works for my purposes.

I am still wondering if anyone has run into the same issue and found 
other solutions.
