Is your feature request related to a problem? Please describe.

It would be awesome if opts.[direction].title can accept a string and a function (the functions must return a string).

Two use cases:

bottom = {
    {
        -- Indicate in the windbar which help file is currently open
        title = function() local bufname = vim.api.nvim_buf_get_name(0)
            bufname = vim.fn.fnamemodify(bufname, ':t')
            return string.format('HELP: %s', bufname)
        end,
        ft = 'help',
    },
    {
        -- Indicate whether the location list or quickfix list is currently
        -- displayed
        title = function()
            local loclist = vim.fn.getwininfo(vim.fn.win_getid())[1]['loclist'] == 1
            return loclist and 'LOCATION LIST' or 'QUICKFIX LIST'
        end,
        ft = 'qf',
    }
}

Describe the solution you'd like

opts.[direction].title accepts string and function

Describe alternatives you've considered

Disabling the winbar winbar = false for a filetype and handling it manually with my winbar plugin. However this is a workaround and i'd love to handle all the winbar titles in edgy.nvim

I realized I can solve the second use case with the filter() function:

{
    title = 'QUICKFIX LIST',
    filter = function(_, win)
        return vim.fn.getwininfo(win)[1]['loclist'] ~= 1
    end,
    ft = 'qf',
},
{
    title = 'LOCATION LIST',
    filter = function(_, win)
        return vim.fn.getwininfo(win)[1]['loclist'] == 1
    end,
    ft = 'qf',
},

However, in cases where a single filetype covers various instances, like help documents and manpages, it would be very helpful to have the filename or bufname included in the winbar information. This feature request is kindly submitted for consideration, aiming to enhance user experience.
