Please add child/parent tabs

[bluefiberbread]

It would make things so much easier

[Croydon]

Could you explain this please further?

Do you want to have a tree view so that you have an indentation for child tabs?

[bluefiberbread]

Basically the parent tab is created when you open another tab from it, and so on, and you can move tabs to other parent/child tabs

[Croydon]

Firefox is already remembering what the parent tabs are, so technically it is already there.

You don't make it very clear if and how you want to have this visualized, so I'm assuming you want to have a tree view?

[Croydon]

In the case of a tree view this is pretty much out of scope for VTR right now and I would recommend add-ons which are specialized on tab tree views.
