Tabs, as understood by any other editor.
barbar.nvim is a tabline plugin with re-orderable tabs, icons, nice highlighting,
sort-by commands, and a magic jump-to-buffer mode.
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
Is two dependencies a lot 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/lib.kom'
Plug 'romgrk/barbar.nvim'You can skip the dependency on 'kyazdani42/nvim-web-devicons' if you
disable icons.
I might remove the dependencies in the future if I have enough time to port the required functions, or if you complain loud enough.

let bg_current = get(nvim_get_hl_by_name('Normal', 1), 'background', '#000000')
let bg_visible = get(nvim_get_hl_by_name('TabLineSel', 1), 'background', '#000000')
let bg_inactive = get(nvim_get_hl_by_name('TabLine', 1), 'background', '#000000')
" For the current active buffer
hi default link BufferCurrent Normal
" For the current active buffer when modified
hi default link BufferCurrentMod Normal
" For the current active buffer icon
hi default link BufferCurrentSign Normal
" For the current active buffer target when buffer-picking
exe 'hi default BufferCurrentTarget guifg=red gui=bold guibg=' . bg_current
" For buffers visible but not the current one
hi default link BufferVisible TabLineSel
hi default link BufferVisibleMod TabLineSel

" For the shadow in buffer-picking mode

" If set, the letters for each buffer in buffer-pick mode will be
