Hi all again, 

While I try how to debug my plugin with Chimera (I posted that question here), I downloaded the 'Fit in map' tool source code to create my own plugin from it. So I changed the name in ChimeraExtension.py and loaded it in Tools -> Volume Data to check that my new plugin was loaded succesfully.

The point now is that when I make some changes in my code, they are not immediately visible when I open the plugin again. Even more, I am not capable to "reload" the plugin with the new changes.

Any solution to this? As I told you before, I'm fully newbie with Chimera and I feel pretty lost

Thank you in advance!
