multi-run now supports opening multiple remote files with TRAMP:
(defun multi-run-find-remote-files (file-path &optional window-batch)
"Open file specified by FILE-PATH for all terminals and display them on the screen with WINDOW-BATCH number of them in one single vertical slot.")
(defun multi-run-find-remote-files-sudo (file-path &optional window-batch non-root)
"Open file specified by FILE-PATH for all terminals and display them on the screen with WINDOW-BATCH number of them in one single vertical slot. Open with sudo if NON-ROOT is false.")
