Dear Jacque,

I know too well the rabbit holes that lies deep into some LC projects. 
As Richard have guessed, by using a ton of behaviors and libraries, you 
can end up with code that you can't easily trace and also which becomes 
quite hard to debug. As Jacque and I worked on the same project, one 
that is quite hard to debug on mobile, I came to realize that we needed 
some better tools.

To solve that I made a "Network Tracer" tool to help me debug exact 
those apps. Think of it as a message box with more features, allowing 
you to not only display text and variable contents but also trace back 
where those texts are coming from. The network tracer work over LAN so 
you can have the phone and LC IDE on the same wifi network and should 
just work. I made a video showing it working at:

There is more information about it at my homepage at:
