Finally… FINALLY Protege ontology builder has the ability to create sibling classes. It’s a new feature in the newish stable release, 3.0. For a year almost, after the ontology has grown to such proportions that the subclasses of some classes don’t fit in the window (not even on 1280×1024) , it’s been such a pain in the neck to scroll up and down everytime I want to make a new class.

Until now.

How can something so little (the icon) be so powerful and wonderful, and save several moments of argh-ness?
