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!!

TST has no such option and I have no plan to implement it as a built-in feature due to the project policy, so it need to be provided by something other extensions. TST More Tree Commands is one of them, but sorry I'm not active to maintain it - the PR to implement the feature is welcome.
