Hi Eli,

Thanks. You are right, vanilla ​Emacs indeed recenters a new file by
default.
I'm using spacemacs, which won't and I'm investigating the problem.


If the file is already visited in Emacs, it won't recenter. Is it possible
to make
Emacs recenter even if it's already visited? I've check with Notepad++,
which
will recenter even if it's already opened.

Best,
Xiaolong
