Close tabs after add to bookmarks

[ratio-dd]

I always use "add whole tab tree to bookmarks" when my tab tree get messy, and I want to handle some tree later.
I just add them to the bookmarks and close the whole tree. I wonder is there a exist setting that can auto close tabs after add them to the bookmarks?

I use Multiple Tab Handler as well to manually create folder in tab tree. But when I close the whole tree (with many folder inside), many confirm window will pop up as I close a folder before it's children are closed. So I want to know is there a better setting for me to do the "add to bookmarks -> close all" workflow?

The description may be chaos so if anyone need more information about what I do, just @me. Thanks!!
