2of3, I understand & expected the question.
Too much time invested in gaining reasonable proficiency with SKS5 to not keep it around for quick&dirty tweeks to skins. SKS7 will be for 'play' for quite a while, I'm afraid, particularly since all my rigs are still running XP, so I may just wait for the 'server end to be set correctly' to be sure SKS5 doesn't get borked unintentionally. Soon as it's 'safe' to install 7 leaving 5 in place, I'll dive in.
I hear ya. I do feel that if you gave sks7 a chance, you may discover that it is pretty good for just that too: quick tweaks as well as full skinning (I too started out on sks5 at was very reluctant to go over to version 6). Glad you are able to keep the version you are used to, though.
