Working with multiple taxonomy select

I need taxonomySearch module for selecting nodes from multiple terms at one time. Current version can select only one term.
I have modify sources to add ability to select nodes more than from one term.
And add protection to removing already selected nodes from older node editions.
Maybe my modifications need testing and optimizing, but it works good for me. Maybe they helps anything else.

Will be good to see this functional in future oficial versions of module!
