Well he's released the new version, I just forgot to mention it!
Changes in this version:
- Added Service Manager support
- Change to grid views
- Clear grid option
- More compare options
- Colors changed to help visibility
- Management group versions added
It works well and I've litterally just finished using it to ensure all the MP's are sync'd up between SCOM & SCSM after Rob installed CU3 for SCOM the other week.
