[John Maloney]

Add a dropdown menu to variable reporters allowing them to be switched to a different variable in place. (Suggested by Roger Wagner.)

Tom Lauwers uses this feature extensively in his Hummingbird library. It is also used in the Maqueen robot library. I have searched the Microblocks.fun and Wiki sites to find out how to use this feature. I have also inspected block definitions in both the Hummingbird and Maqueen libraries to see how they used this feature.

I have not yet been able figure out how it is done. Can you point a reference or example that will illustrate its implementation? Thank you.

I may have found an answer to my own question: The .ubl files are editable text files that can be enhanced with features not accessible in the IDE.

I’ll see what I can do with that insight.
