I am either confused or the implementation of this feature went very wrong...

The puzzle piece icon is only on KLC, not KRC.  Therefore I cannot launch my 'extensions' in an RC session.  If I launch them from the KLC window, I only get a 'script error' that quickly disappears.  

It seems like this is supposed to be available on the KRC window so that you can launch your tools while actively controlling the machine.

If the intention is only to use this from the KLC window, then anything launched would need to be a fully-silent / non-interactive application, right? But since there is nowhere to add switches... it would need to be a .bat file or a pre-configured custom .exe?

And the download function downloads it to your local machine, not the controlled machine... so... 

I don't get it.  Seems useless.  Please help :)
