I'm working on the Pharo debugger, and I wanted to add a button with new functionality just besides the buttons "Proceed" "restart" ...

Is there an easy way to do it? Which is the class that I have to Modify/Extend in order to do that?

I tried to look around the methods and I found where DebugSession is created, but I didn't see any clear reference to the UI or to how is constructed in it.

Thank you in advance,

Matteo
