Thanks, Ben.. The bt=help is probably what I was looking for.

I'll set this up via a custom :Help command that will additionally take
care of removing the scratch buffers. And possibly add some logic that
counts the number of help windows in the current tab.. if zero: create
a new tab, if one: do a vertical split on the current tab.. and if two
or more... do horizontal splits.

Not very flexible but it should cover my limited needs.

How could I figure out the number of help windows in the current tab?

Thanks,
