This should have been fixed.  The name generated by the CIDL compiler was
changed.  So it's likely that the version of the idl_to_picml.exe that you
had is old.

There isn't any benefit to importing CIDL files into the model(yet).  It
might be worthwhile to automatically generate the CIDL elements as well
from the IDL importer so that it is not tedious.

This is a quirk of using GME's set mode.  There is no way getting around
it, but I am surprised that you mention lack of visible guide.  Are you
sure that you have compiled PICML's decorator?  Jeff fixed this problem
long ago.  BTW, which version of CoSMIC are you using?

The difference is historic and not worth knowing.  BTW, a deployment plan
is *flat*.  Always.  So *flattened deployment plan* doesn't make sense.
This should also get fixed in the next release of CoSMIC.

It is not useful anymore.  It used to be sometime in the past...

Hope this helps.
