Incorrect tabs tree on opening bookmarks

[OmTatSat]

Description

When i bookmark tabs tree it will create groups for all sub trees, and when i will restore it will create not exactlyly what i see before bookmarking. After restore, I want ability have all sub tab trees but without groups folders near every sub tree, is it posible?

Also in bookmarks i want to see not only group name but also all tabs in sub trees.

Also ability to restore tree in exact panel and place it after active tab. Without loading restored tabs before i activate them, and with icons from bookmarks.

Also, i think good alternative would be some enhancements to session administration, like: have ability to see sessions in sidebar like extra panel with bookmarks but with sessions in it. have ability to restore only selected part of sesssion have ability to save separate session to protect it from auto deletion.
