On my first time with a Mac, I had no problem and imediately understood 
what the disclosure tringle was for.
But the first time I saw this "+" and "-" thing on Win95 I imediately 
thought that's stupid, how should one be able to tell if it refers to the 
current state or the action to take place on clicking. (No, I'm not making 
this up, believe me!)
The triangle appears as one widget. It turns, but doesn't change otherwise. 
That might be part of the reason that it just works, without letting one 
think much about state or action indication.
It's elegant. (It's not from Microsoft ... :)
There are already disclosure triangles in Blender. Don't introduce something 
else for the same task. The only limitation is that it should only be used 
for things that will show up below it. And it's best to have something like 
a headline to the right. 
Buttonpanels in horizontal mode are a special case. Not perfect, but 
reasonable, because switching means of disclosure between layout modes 
wouldn't be nice.
