When transfering my projects to TMG I kept getting a odd Tag in TMG called HTML. Turns out that some many versions back there was a feature that you could link two projects together if the person was in both projects. Never did see how that this would work, but that is water over the bridge now. Thing is this field is now in the Misc set of Misc screens. Called Weblink. I found those used by searching Ind > Misc > Weblink and typing in the other project name.
Good thing I only used it a few times when starting long ago. At that time I had a project for my wife and one for myself which I continued. Looks like a easy job to merge the files in TMG because the libraries are different now.
UFT users will find some items they had forgot about when the transfer is made to TMG. Because TMG will show everything on the screen, unless full, then you can scroll down for more.
