What plugin provides the subtab feature in NvChad?

Question

There are the normal Neovim tabs but also some small tabs but I have hard time configuring the behavior of those.

Answer 1

I believe they are controlled via the tabline option.

In NvChad the option is set the the callback tabbufline from the nvchad_ui plugin.

The NvChad documentation has a special paragraph to document what can be done on tabline
