Dingo,

Version 2.2 just uploaded to the AFL Library.

That is a good idea.  If I had a non-displayable character that was  
still recognizable by AB as part of a name, then I could  
automatically append another character for each new top level menu.   
I already use "." and "_"  and spacing for real things to align  
indents etc., so a non printable would be ideal.

While experimenting, I noticed that some characters (like "\" or "&")  
displayed other things in the label --it seems all characters are not  
treated equally.  It looks like they may be treated like a text  
command escape sequence or something.  Leading and trailing blanks  
are removed from a name, and a tab char embedded will display a  
section header.  My experimenting did not yield any good prospects.

However, a light bulb went off in the process, and I realized through  
a bit of experimenting that I can have half my cake and eat it too!

If I treat the _Section_Begin("SectionName"); command as just an AFL  
command to display a section header, and create the unique names for  
the section, I can make them conditionally pop up and say what I  
want, when I want it.  So, I can replace the top level menu with a  
section divider when it is open, to make the sections stand out, AND  
make the names unique.  I do not have to have a _Section_End command  
to make this work.  This is cool and is 90% of what I wanted to get.   
I still have to use up one param slot below an open section to close  
it, but that is not too bad.

I just have to keep in mind that using params this way is not meant  
for the kind of drag and drop functionality built into AB at the UI  
level, but more as a complete custom user interface for a complex  
system.  Each has its place.

If I could tell what state the native top level param section is in  
(open or closed) or alternatively, that it was clicked on like a  
ParamTrigger(), I could even get 98% of what I want.

Tomasz put a lot more flexibility into the way Params and Sections  
work than I realized when I started this task --I just can't quite  
get a hook into everything I would like to make this seamless.   
Unfortunately, the next change TJ makes to the Params window could  
break my methods if he does not make a specific allowance for them or  
an alternative.  That is the risk of coding on the edge.

Version 2.2 just uploaded to the AFL Library.

Thanks,
Dennis
