[QUESTION]: Group windows inside a single tab?

[ls-devs]

Hi,
I was wondering if it is possible to have two windows inside a single tab ?

Let's say I have tab1 with two windows split vertically or horizontally and I have another tab, tab2 with only one window and I switch back to tab1 it retores the two splitted windows ?

I think there is some confusion between what barbar calls a "tab", which is equivalent to a listed vim buffer, and what vim calls a "tabpage", which is a window layout. Barbar doesn't use tabpages, it shows one tab for each buffer. You can also use tabpages.

As above, see :h windows-intro. Here is a brief summary:

A buffer is the in-memory text of a file.
A window is a viewport on a buffer.
A tab page is a collection of windows.
