I've been slowly becoming more evil ever since I learned you can have terminals in gvim.

function :e () {
    gvim --remote-send '<C-W>:e '"$(realpath "$1")"'<CR>'
}

function command_not_found_handle () 
{ 
    case "$1" in :*) gvim --remote-send '<C-W>'"$*"'<CR>'; return 0;; esac

    /usr/lib/command-not-found -- "$1";
    return $?;
}
