In the impossibility to move the status line to the top as it was stated on the accepted answer, this might help.
Set this on your vim config:
set title - will set the title on the current file on the terminal window at the top
let mapleader="\<space>" - defines a leader key to enter your own defined shortcuts mappings
nnoremap <Tab> :bnext<CR> - goes to next buffer by pressing Tab
nnoremap <S-Tab> :bprevious<CR> - goes to previous buffer by pressing Shift+Tab
bling/vim-bufferline - use the bufferline plugin to always get a list of your opened buffers at the bottom
nonoremap <leader>1 :b1<CR>
nonoremap <leader>2 :b2<CR>
nonoremap <leader>N :bN<CR>...
get to the buffer you want just pressing space + number
One thing that I'm looking for though is to have one directory up in conjunction with the filename on bufferline list. According to its docs it would be change on
let g:bufferline_fname_mod = ':t' and looking at the
:h filename-modifiers it would be
let g:bufferline_fname_mod = ':p:.' but I didn't have success in that.
