Right now, when I split a file in VIM, I need to use
CTRL-W + h/j/k/l to switch between them.
In spacevim (https://spacevim.org/), each file has a number visible in the bar (see picture), and I can just press
SPACE + <number> in command mode to go to that file. I find that way more convenient than the default
CTRL-W option. However, I don't want to install spacevim just for this, because it do a lot of other config that I don't like.
So how could I configure my vimrc to do the same?
Thank in advance for your help.
