I agree with you, personally, but I don't think this particular bit
(:hide-empty-searches) increases code complexity that much (and all of
it is localized to the functions generating the sections, which possibly
should be moved to a separate file). I also find it plausible that a
user might want behavior like this (as, e.g. an overview, if he doesn't
want an all tags section, but still see what tags he has set).

Hence I don't see why we should not provide this option.

As I said, this is not my preference either, but personal taste is not
necessarily the best argument for _not including_ something, especially
for the UI of a mail client. And in this case there even is someone
saying that behavior would be useful to him.

Yes, me too, but I like seeing only sections that I care about every
time I open notmuch while still having more information available in a
convenient way. But I'm not too attached to this feature, so if the
consensus is that that bit should be removed, I'll bow to public opinion. :)

Ah, I misunderstood what you were referring to earlier. That was already
case before my patch though, except that now it's more likely to have
buttons with the same name. Anyway, I think this is just a minor issue
and can be addressed in a different patch.

In any event, this definitely needs better documentation.

Thanks for all your input on this!

Cheers,
Daniel
