The weights are a bit heavy, and I had to move them to column 65 to make
them fit in a vertically splitted screen. But they carry more
information of course, the question is if one can process this
information quickly enough, or if one single number is not enough to
give an impression of the subtrees 'weight'. Or maybe

is easier on the eyes than

It would be easy to make the position of the weight/cookie a user option
- either direcctly behind the headline text, or aligned at a certain

I would still like to have my original idea (which was actually a user
request for outshine.el by Jonas Bernoulli): show the number of hidden
lines only when the headline is folded, and update with every visibility

This task seems to bring Emacs to its limits, at least in 5000+ lines
outshine buffers (e.g. my init.el). 

So maybe its not that suited for a visibility-change hook, but rather
for occasional activation by an explicit user command?
