Recently i playing widht the NLA and when i do some seriously animation the
NLA strips count growing up too much and it is hard to handle the strips.
I Thinking about that if i select some NLA strips and make a parent they will be grupped someting like in Outliner window when i parenting two objects and for this NLA Groups if i can turn on/off mute attribute simultaneously it would be help a lot for animators.
Thanks yes i know that, but for now for my character have 27 NLA strips within 80 frames because i separating for lips synchron - facemimic - eye look - body poses etc this way more easy timing and tuning-in the animations later than if i make a long NLA strips were i put all together this animations parts and if i can Gupping this NLA-s together i can handle NLA-s more easily.
