in vimfiler, the first line is:
[in] /home/wsdjeg/SpaceVim
I hope vimfiler provide a option to set the text. we can use a funcref as the value of the func. and call this func with one argv (path). then return the text which will be used as title.
see the picture in emacs.

Sorry, I don't want to add the feature in vimfiler.
Because I should create the new file explorer instead.
Yeah, That would be better, hope this feature can be implemeneted in the new file explorer plugin.
OK. Todo listed in defx.nvim.
Thanks
