For those of you who don't know, MDT (Magik Development Tools) is a visual Integrated Development Environment for Smallworld developers that is based on the Eclipse framework. You can read more about the details here.
I think that it promises faster familiarization with Magik particularly for those developers just getting started. I have to admit that it took me quite a while to get comfortable with Emacs.
I haven't used the tool much myself, but would love to hear from users that have made the switch from Emacs to MDT to learn about their experiences.
