Just viewing the User tools page in options creates a new tool. After just viewing that page theres a dummy tool called "New Tool" in the tools menu and removing this tool doesn't seem to be possible.
This probably only happens if there is no other user tools.
Viewing the new User tools page...

This topic should be in the "Compare It! : beta section". The problem I described is in the Compare It! 4.0 RC not in Synchronize It!. Don't know how I posted this so off.
