Michalis,
No doubt you are referring to Blender's UV editor. I've had a good look at it ( including your tutorials ) and there's no doubt about it - there's a much greater control over the placement of UVs and Islands in this editor.
One day I will be using this for "better control" over UVs, but meanwhile ZB's UV protocols I think can still do wonders...
Thanx for the encouragements ( and Displacement Maps ).
[ And I agree : Rira bien qui rira le dernier...]
