Hi Piro,
In the Group View of TST More Tree Commands (Operate Tree > Create New Group from tabs), can you support:
[1] render lines (vertical,horizontal) representing the hierarchical relationship between various nodes.
[2] has option to view in one column with vertical scrollbar, and the ability to set column width.
Here is my screenshot:

My situation is:
I watch dolphin, porpoise on YouTube and look up information from many sources, including Wiki.
(1) I cannot edit the tab title, for example: re-title the tab "Toothed whale - Wikipedia" into "Parvorder Odontocetes (Odontoceti) = Toothed whale".
(2) Besides English wiki (with standard hierarchy), I also read in other language (Vietnamese).
=> I grouped tabs wiki English and Vietnamese, then name the group as desired.
Thank you very much!
Good health!
