Tree style Tab bar Add-on for Opera web browser
 

Opera 10.62

I am looking for a Tree style tab bar plugin/add-on for Opera. I searched Get Widgets option but couldn't find much.

Kindly help !

You should mention your support on this page of the official Opera forums:

That thread is dated 2010, and they have quite
enough supporters for that feature there. ;-)

Thanks, Anisha. This thread comes up in the first search results when Googling for this feature. The Opera devs usually implement features based on demand, so I found it prudent to direct those looking for the feature to the correct place to request it.

In other words, my answer was more for future searchers than for the OP.

Use the Opera's windows panel to organise tabs. It will show windows, tabs and tab stacks in a tree format.

That provides but a single level of nesting, and each top-level "tab" is a separate Opera window! Surely you jest.

two levels. The windows and then the tab stacks within them
