I just thought it works like: Ckknight has his own base for addons. And some options are only opened and some locked. There is many similarities in addons (even for different processes like unit frame, combat text, chat mod...). So I thought FrameStrata is just an option which is kind of "locked". Its pitty I dont have time to create or co-create and improve addons. Wow itself is enough time consuming activity.
In the end I want to thank to Ckknight his addons (Pitbull, Parot) are simply the best. I have tried many addons so far in last 3 yars of playing (Like: CT, Pearl, X-Pearl, AGuF...SCT, MSBT..) but king is only one. Good job knight.
