Hi Lou,

Thanks for writing! Your idea seems like a reasonable extension, and
also is consistent with other programs (e.g., I know tiling window
managers have this type of flexible splitting). That said, it is the
first time I have heard of this request from a user, so I don't know if
developers will place it as a high priority. I think the main question
is: would you be willing to work on a patch? Don't work on it yet (since
we should wait for the opinions of other developers).

Also just to get a feeling for your use case, what would be your most
common desired setup? 2x2 with equal sizes? Or split vertical and then
split horizontal on one half but not the other? Hopefully your desired
setup could be achieved with a simple "command-sequence". I forget, is
it easy to use an LFUN to move the cursor from one view to another?
