How to split my tree if I need to manage thousands of pages and hundreds of categories?

Hello, If my site is huge. My tree has more than 4 levels. 

more often I need to maintain some of the branches.

Can I split my tree? Or you have a better solution? Thanks a lot!

In ListerPro (commercial)  you can add bookmarks so you can directly open one page as the root tree (as I know, I don't have ListerPro). You can achieve something similar with AdminOnSteroids module's NavItems tweak too.

Thank you TPR!  AdminOnSteroids is a good solution.
