Wouldn't it be nice to finish writing a class or procedure and have a simple button that would tell you if any of the variables were unused?
Isn't this the same as what you've added here: community.progress.com/.../unused_code.aspx ?
Oedt plugin seems to provide this somewhat... Message to Progress: please buy this plugin and provide this functionality by default, this is essential!
Will be included in OE 12 using SonarLint functionality I assume...
