Is there a way to save the current buffer position on a per-window basis, instead of just a per-buffer basis? For example, the following will move point in both windows to the same location
Split-window Navigate to same file in both windows
In one window, move to a different location. Then, call describe-function, which uses the other window. Switch to the *help* window and go back to the original location. The old point is lost and replaced with the point in the other buffer.
Is there a way to have the old point location be saved, even if it is not displayed at the moment?
