The Standard Extension Support Level enables logging the extension functions calls and arguments, setting breakpoints at the extension functions and watching the extension states variables values.
In addition to the Standard Extension Support Level features, the Full Extension Support Level enables viewing the extension related data in the appropriate gDEBugger views.
If you use or plan on using an extension not currently supported by gDEBugger, send an email to the . Your extension support will receive higher priority.
