So it should reduce I/O. I gave it a shot for both local
and remote frontends. It seem a little quicker locally
but it still isn't practical for a remote frontend. I'm
not suggesting you tweak it for remote frontends, I just
don't think seeking remotely will ever work as well as
setting JumpAmount to 4 and hitting PageUp. However,
blank frame lists should work exactly the same for either
local or remote.

Right. It'll be a tiny file that has virtually no impact
on disk space or throughput.
