Again - each to their own. You obviously understood everything about WL7 at first launch…lucky you.
But I use WL7 daily and despite not needing the manual every day - there were times that the “shock” of WL7 (and getting around in it in the early stages) were a complete PITA without proper, VERY detailed documentation.
Even today - some 2+ years after WL7 - I still do not know how to do many things and in the spirit of being able to work - I just stick with the two workspaces that I know how to use and I never modify anything. Clicking on anything else - simply takes me to a place that I do not want to be.
So a full manual for V8 will be a huge help - to me anyway.
