Animations blend phases

Would like to address this topic more time, despite the fact that it has disclosed in article in the resource gamedev.ru and sources there is also attached. But perhaps someone will share their ideas for the development of this plug-in, as indeed it is very useful in the animations transitions. Here for example a standard MoBu Triggering tree does not have this functionality, but in vain.
