I "second" Bob's (BW's) suggestion. I had to post a message in the forums to find the SDK. After I had searched for quite a while. The menu system was confusing me. A single "developer" link from the menu with a splash page explaining the different options (plug-in's, scripts, MachRemote, etc) would be a HUGE time saver for developers tasked with automating/customizing Mach3.
