问题
I would like for vim to show the tab header (tab line) even if only one file is open.
For example, I open a file using vim. Then, I use :tabnew to open another file in a vim tab. Vim then displays a nice tab header at the top of the file. I would like this tab header to always be displayed (i.e. even if only one file is open in vim).
Also, not really a fan of the airline plugins, so not really looking for those kinds of answers.

Yes sorry about that. I was doing :help tabline and didn't see anything. You just need to put set showtabline=2 in your vimrc
