Yeah gster, like it had not occered to me to read the manual. I guess if you like reading 3 pages of techno-babble that could just as easily be explained with one or two simple examples. Half the manual help pages read like...

UV fold - Used to unfold uvs. The selected uvs are unfolded. ... and fifteen more sentences that says uv unfold unfolds uvs. Okay, that's great I just read 20 sentences and I now know uv unfold unfolds uvs. But I still have no freaking clue how to use it or its 50 option properties! I don't need to know what a tool does! I need to know HOW and WHEN to use it!

Also, F1 explains each tool independently and says nothing about workflow and how they are used together.

Read the help on "uv unfold" with no prior knowledge of uv mapping and it may as well be written in ancient sumarian.
