Well, (only for testing purposes) I have Installed the Firewall without Defense+
(I selected only Firewall without leak protection in the installer).
I find it confusing that there is no obvious visual indiaction that D+ is disabled.It would be nice to make it nocticable at first sight that D+ is disabled.
For example, the D+ GUI could be "greyed out", A message like
"Defence+ is disabled" together with an
"Enable Defense+" Button could be displayed
in the D+ Window.
That would make things much clearer.
And while we're at it It should also be indicated if D+ is in "optimum protection"
or "network protection" (=Leakproof Firewall) mode.
So we would have three status messages in the D+ main window:1) Defense+ is enabled and in Optimum Protecton mode
2) Defense+ is enabled and in Network Protection mode
3) Defense+ is currently disabled.
As I said, the way it is now without any information being displayed is quite
confusing. 
Best regards.
