I have one question though. Is there a tool that can tell what settings are applied to the plugin? In the log above, there's 7 ports that have to be set, that's why there's the default value. Also there's two other ports that weren't set anywhere, so I think they're not taken into consideration at all if they're not set in the control= option. I just wanted to see whether the settings in control=1,1.5,401,-30,20,5,12 are properly set. Is there something like that? -----BEGIN PGP SIGNATURE----- iQIcBAEBCgAGBQJWCj/iAAoJEM0EaBB3G2Ugo3QP/jfF+mi2+2nrxENjyQCLg56O bPwVTeFBz2hC23RFeCLnHZ4SjXZK0JygteslpbpvdptL2jZtxANFhqZXfqOeMdOI afN6lRIIcqhASSIkjFmBHb0Hmj5v272PV/yB8yOWN4xXNu76L0vdd2YntMu0c3mF ZWofO3PU4acaZE5tHyH07LQHFjokmxP2hepPeuU2kC5JZHBBdGXAfttKN/9jQX+f I93SoH5ycazvXHJcUIEX5xfH6Zi0MQC2ZaxQ7IOK+Wk/rpboToMSq5cZwI5Nnblf T2R0Z7PrCAF7AIUg2X0eLC79Tb/ru8tq7wKUf1onGRN63sFylzBTXVGBsywgDVBK ysQPY3KQ0eAnt54D6NtGGqSKJ2WSB8S+EgwaRLd5lSL3JwuTQfXOOfJSMttaNhVa ogaVtbUjig8WFIDoz9NZO/t3kgN5edINwjas6l+2LAu+kBNEHN8ESIq4auW+EKRv p3fcWeqDG4/j4450MpEW5YDgjyrDTGwS7Kw5GKaPoG2Hdt2SYbeLNudpofNQHu/e tRvrjKtfdZ11LjV7c9AtFcXyigQSUhGDH7dojoZ0MBDAlTEncQ/Reah+Hh6lt2PF yve4Q2ye4PmZW/YP74nMOq7iNBz+H4LqHxXohf51iQoOD7jcuHIesEIWErWH73hT jx3GtmoXGu8zkq1MxiLZ =gHDf -----END PGP SIGNATURE-----
