Is it possible to reopen closed window in vim, that was in split?
Something like ctrl+shift+t with browser tabs?
I've gotten this to work by using bufmru.vim!
The following command, :ReopenLastTab, will re-split the last-open buffer:
command ReopenLastTab execute "vsplit" bufname(g:bufmru_bnrs[1])
I installed bufmru using Vundle, as below, but of course you can install it any way you like.
#.vimrc
" Install bufmru with Vundle
Plugin 'vim-scripts/bufmru.vim'
let g:bufmru_switchkey = "" " I never use this: the default is Space, but I don't need to use it so set it to something I don't care about.
