Yes, Grouping the tab groups, will reduce the multiple groups and easy to manage same topic's root topics. It will be first in browser world too, it will be fox move.
I would like to see is the ability to have subgroups. Example, I want to group all tabs related to landscape ideas I am looking to do at my house, but I want to group tabs that relate to different ideas. LANDSCAPE (group) - FLOWERS (subgroup) - PLANTS (subgroup) - TREES (subgroup).
Hi, @CUsoon , just in case: you could check the Sidebery add-on, which works wonders for the administration of many tabs.
I see an increasing convergence between native tab administration and Sidebery way, because of user-cases like the one you mention.
Maybe in the future Firefox adopt Sidebery and users could choose/activate an optional "Power Tab User" in order to keep a simple tab method for most users and a more Sidebery method for a more intense one.
Anyway, grouping tab groups (or sub-grouping a group) seems like a naturally occurring necessity, I guess.
I think once you started grouping tabs the multi-window approach becomes redundant.
Anyway, Firefox never added the possibility to name windows..., so, now it seems late.
For the grouping of groups we also have the Sidebery add-on.
Maybe won't be a balance between "simple-users" and "power-users", and we end with an option like "Power Tab User" that activates a native form of Sidebery on Firefox...
