Yes, you've mentioned this before, very tricky and
still a problem for the fmt=#group template isn't it?

I don't understand this, maybe I'm too dense, could
you give an example?

Now that sounds like a neat idea! So the group
template could look like this:
[[#group]]
(:if ! equal {=$Group} {<$Group}:)
(:increment-count:)
* [[{=$Group}/]]
[[#groupend]]
But, then how does it know that in other cases when
someone does not specify an (:increment-count:)
directive in a template that the count should always
be incremented? Maybe not as intuitive, but an
alternative would be to use a directive instead to
indicate the need to NOT increment the count, maybe
like this?:
[[#group]]
(:if ! equal {=$Group} {<$Group}:)
* [[{=$Group}/]]
(:if equal {=$Group} {<$Group}:)
(:skip-count:)
[[#groupend]]
...but, I think that's ugly! :) I guess you could
pre-scan the template and if there is no
(:increment-count:) directive anywhere, automatically
increase the count on each iteration?
What about all the new suggestions of having special
grouping options within templates, could the
(:increment-count:) type directive be used to control
the count within the individual groupings?
(:increment-count name:)
(:increment-count department:)
