Tabs, as understood by any other editor.
barbar.nvim is a tabline plugin with re-orderable, auto-sizing, clickable tabs,
icons, nice highlighting, sort-by commands and a magic jump-to-buffer mode. Plus
the tab names are made unique when two filenames match.
In jump-to-buffer mode, tabs display a target letter instead of their icon. Jump to any buffer by simply typing their target letter. Even better, the target letter stays constant for the lifetime of the buffer, so if you're working with a set of files you can even type the letter ahead from memory.
Letters stay constant for the lifetime of the buffer. By default, letters are assigned
based on buffer name, eg README will get letter r. You can change this so that
letters are assigned based on usability: home row (asdfjkl;gh) first, then other rows.
:BufferOrderByDirectory and :BufferOrderByLanguage
Left-click to go, middle-click or close button to close.
A modified version of bbye.vim is included in this
plugin to close buffers without messing with your window layout and more. Available
as BufferClose and bufferline#bbye#delete(buf).
Is one dependency bad for one plugin? Yes it is. But is Barbar a very good tabline plugin? Also yes. Do you now understand why the Install section is strategically placed after the cool demos? Yes again.
Plug 'kyazdani42/nvim-web-devicons'
Plug 'romgrk/barbar.nvim'You can skip the dependency on 'kyazdani42/nvim-web-devicons' if you
disable icons. If you want the icons, don't forget to
install nerd fonts.

No default mappings are provided, here is an example. It is recommended to use
the BufferClose command to close buffers instead of bdelete because it will
not mess your window layout.

For the highlight groups, here are the default ones. Your colorscheme can override them by defining them. See the "Meaning of terms" comment inside the example below.
let fg_target = 'red'
let fg_current = s:fg(['Normal'], '#efefef')
let fg_visible = s:fg(['TabLineSel'], '#efefef')
let fg_inactive = s:fg(['TabLineFill'], '#888888')
let fg_modified = s:fg(['WarningMsg'], '#E5AB0E')
let fg_special = s:fg(['Special'], '#599eff')
let fg_subtle = s:fg(['NonText', 'Comment'], '#555555')
let bg_current = s:bg(['Normal'], '#000000')
let bg_visible = s:bg(['TabLineSel', 'Normal'], '#000000')
let bg_inactive = s:bg(['TabLineFill', 'StatusLine'], '#000000')

You can also use the doom-one.vim colorscheme that defines those groups and is also very pleasant as you could see in the demos above.
BufferNext/BufferPrevious don't work in netrw buffer due to an issue in
netrw. See this comment
for a workaround.
Barbar is called barbar because it's a bar, but it's also more than a bar: a "barbar".
It is pronounced like "Jar Jar" in "Jar Jar Binks", but with Bs.
No, barbar has nothing to do with barbarians.
