I often keep a "short" secondary window below my main window with an arrangement like so:
+---------+ | | | | | top | | | | | | | +---------+ | | | bottom | | | +---------+
The bottom window typically contains,
*Help*, etc. I typically keep a 80%-20% top-bottom split, but I find myself having to maintain this manually. Whenever I open certain new mode types like Help they often grow the bottom window to a 50-50 split with top. Is there any way for me to preserve this arrangement even when invoking these alternative modes like Help or compilation?
