This is great, thank you so much!

Agreed. What's your configuration for this simple purpose? What I can
think of is something like the following:

;; Split windows horizontally and display the PDF and TeX source side-by-side
(setq split-width-threshold 1000)
(add-hook 'TeX-after-compilation-finished-functions
          #'(lambda () (pdf-tools-deactivate-strip)))

Any enhancements/comments will be appreciated.
