Add a keyword to all the papco_panel widgets "widgetInfo" that is a widget to which the widget tags are concatenated. This would declutter the panel editors, which have create_structs interleaved between each of the widgets.
I've added the keyword to most widgets, and if we decide it's not causing new problems, I'll do the rest.
onera_cdf's panel shows how this makes the panel editor code much more readable.
One potential pitfall is if a novice has a duplicated keyword, then the cat_struct will fail inside the papco core code, probably generating a service request. However this also gives the opportunity to present a better error message than IDL would have.
