Feature code generator?

There has been some some discussion about a Feature code generator on the RoboFab-group. [url=http://groups.google.com/group/robofab/browse_thread/thread/7365d7c9de6eaf7f][/u rl]

It would be nice to implement some of Tal Lemings’s code into a plugin.
For beginners it’s almost impossible to understand all the technical stuuf about feature lookups and substitutions. And I guess even professional typedesigners have trouble understanding all the details.

Since Glyphs is really a visual fonteditor, making features visual would be a great improvement.
