Hello everybody…
I was search behavior realisation for working with rapidly changing tree.
I find extention by nested set structure, but you know what it’s not fast structure when you insert into the tree.
I dont find realisation at materialized path. I wrote extention for working with materialized path structure as active record behavior.
Now if you need, then welcome…

extention fully tested, you can develop and do not worry somethings broke =)
Thanks for attention
