I first started using FMrobot 0.8.3 in 2005 to copy Tables (or selected field definitions) from one FileMaker database to another. When table cloning became a built-in FileMaker feature, I stopped using FMrobot because FileMaker was so much easier and faster. But I still miss FMrobot's superior reporting when encountering errors (e.g., references to undefined items). Since FileMaker silently turns undefined references into comments, it's easy to overlook these errors.

I'm still using FMrobot, now at 1.7.1 on Mac OS X, because it's the only practical way to copy Custom Functions from one FIleMaker file to another. I have a huge investment in hundreds of Custom Functions, and I can't imagine how I'd manage with raw FileMaker. Copy-n-paste is way too tedious and error-prone.

FMrobot loses a star in my rating because the Mac OS X feature set perpetually lags behind the Windows release.
