Sidebar snippet?

Before I could back up my database I removed everything from the server. Dumb. On that retired domain was a neat snippet for a sidebar that would allow one to select various chunks that were in a specified Category of chunks for inclusion into the sidebar.

I believe it was splittingred who created it? I searched the forums for 30 minutes but didn’t find this very useful snippet. Nor did I find anything in the Extras at MODXCMS.com

Anyone know what the heck I’m talking about? ;-)

Snippet, or TV? http://sottwell.com/tv-input-types.html (about halfway down the page describes using check boxes to select blocks for a sidebar)

Thanks Susan!
