Version 0.3 of package Doc-View-Follow has just been released in GNU ELPA. You can now find it in M-x list-packages RET.
Doc-View-Follow describes itself as: ============================================= Synchronize windows showing the same document ============================================= More at https://elpa.gnu.org/packages/doc-view-follow.html ## Summary: ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ DOC-VIEW-FOLLOW.EL: SYNCHRONIZE WINDOWS SHOWING THE SAME DOCUMENT ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 1 Overview ══════════ doc-view-follow.el provides a minor mode, `doc-view-follow-mode', that automatically synchronizes page navigation between multiple windows displaying the same document (PS/PDF/DVI/DjVu, etc.). This is essentially an analogue of Emacs' built-in `follow-mode', but for document buffers instead rather than text buffers. In particular, this allows for a convenient "book view," with two windows showing consecutive pages side-by-side. ## Recent NEWS: [Not provided 🙁]
