Hey,

first of all: thanks for the warning of using <s-j> and for the
commands, i think they will be useful. I'm still struggeling with your
command, but i'll certainly just need to read more about them. But i
don't think it helps in that situation (at least in the actual state),
because i can increase my command line independently of how many windows
are open or how they are positioned.
The only thing that prevents that behavior is when i have a vertical
split, that uses the whole width.

thanks after all

regards
