There is quite an underground community who used CopyAgent from Connectix and sorely miss it's elegant and simple functionality. It really is something Apple should include in the system.

This app is halfway there. I wonder if it is possible for the developer to intercept finder copy calls and automatically use the app to complete the operation. Also the app seems fairly slow when copying a folder with no changes - it should be almost instantaneous. Maybe it's the logging overhead. That could probably be done away with since I would think most users would never check the log anyway. A simple dialog box with a short summary would suffice. Even this summary should be an option configurable in the prefs - remember, what the average user really wants is a smarter Finder copy and not several dialog boxes to have to click through.
