I built this version, but sorry, I don't see a live update (live
SMB/fuse mount).

The plot _does_ refresh on pressing the >> or >| buttons, I don't
recall seeing that before.
Update on pressing these buttons is smoother, faster than a full
reload, so it is an improvement.

Forcing polling on all FS whether it's needed (remote) or not (local)
may be unpopular,
is it possible to use stat() to determine file type.
eg on my system:

localfile, remote file:

$ stat --file-system -c %t,%T ~/.bashrc  ~/acq132_055/README.txt

So you could select to poll on all fuseblk files (maybe they don't all
suffer from this problem, but it means that the main case eg ext
doesn't have to.
