I am not sure what they will do with S8 as their is no S8-Classic book yet.

Just to clarifie this: This is not a bug. It is the method how Shredder is
collecting the PV. At least you can be sure that the first move is the one
Shredder really prefers.

I doubt that there is a difference.

Have not tried it with S8 but the S7 UCI in the Classic GUI was about 3 to 5 %
faster than the CB-native on the same comp.
Dont try to calculate the ELO difference :-) . But 5% is the difference between
the two top processors either of AMD or Intel. So its worth about 150€ :-)

F11. You can just play (even automatic) the current PV but no own variant.

No afaik. If you are in analysis mode you do an analysis. So, no play possible.
Interrupt is only interrupting the analysis. It is not making a move. I think
you have to drag and drop by yourself.

If you excactly specify all parameters when a GUI is better you might get an
answer, this is a very personal decission.

From my personal POV I prefer the Classic over all others, because of its a very
ergonomic and intuitiv handling (Right click the windows and you will find
allmost everything that is possible in the classic)
