Buffertag

Buffertag is a very simple plugin which always shows the buffer name in non-focused windows.

This is designed to be used with the set laststatus=3 configuration which removes the unnecessary status lines on each window.

This idea came from enjoying the space saving of set laststatus=3 but missing the ability to quickly reference which buffers are in which windows. I split hard, and I split often.

Usage

Include in Vim Plug (or your package manager of choice)

Plug 'ldelossa/buffertag'

Call setup with an optional config

lua require('buffertag').setup({
    -- accepts any border options that `nvim_open_win` accepts.
    -- see ":help vim.api.nvim_open_win"
    border = "none",
    -- By default if the buffer name is too wide for the pane it's in, it will
    -- display and overlap the pane. By setting this to true, the buffer name will
    -- be truncated to fit within the pane, ensuring the floating window does not
    -- overlap any other panes.
    limit_width = false,
    -- if `vim.bo.modified` is `true` for the current buffer,
    -- display modified symbol before the buffer name.
    modified_symbol = "[+]", -- other modified symbol: "●" 
})

Toggle it on and off
