I think moving to a fixed grid ala Google would be a wiser tiling
system, both because you can re-use the tiles in your own client-side
cache, and you provide the possibility of high-load WMS servers
getting cache advantages themselves by using a cache like squid.

Instead of requesting the entire image on a pan only the areas not
available from the previous render are requested. So if you pan
over a 20 pixels and up 1 then there will be 1 request for 2 pixel
by screen height and 1 request for 1 pixel by screen width. Its
not full tiling yet but if can give a more pleasant panning
experience.
This can be turned off in the preferences if it is annoying or the
WMS puts something like a legend in every render.
