Showing buffer Titles in Tabline when opening multiple files

[Trid-collab]

Could you also share how to show the all buffers (title/name) in tabline in vim. What are the vim settings for the same. Today I get to see the buffer name on the top using "set showtabline=2" when I open a file using tabe, but I open a file using file tree plugin "nvim-tree" it does not show the buffer title in tabline even though when I buffers its shows the files in buffer.

Neovim does not list buffers in the tabline by default. To achieve this you're gonna have to customize your tabline. See :h setting-tabline. There are of course also many plugins that already do this. Take a look at nvim-bufferline and barbar.nvim for instance.

as @sindrets said, take a look at the plugins that aims to provide such feature :)
if you open a file using <C-t> it will show in the tabline because it will open in a new tab
