If you look closer at Studio, you might find that its frontend was based on an older version of GT :). Luke did a nice job on it and he learnt the environment by himself when it was rather crude. How you create contextual tools is secondary. Emacs' ability to create extensions is certainly interesting. But here are some questions to consider: - how many contextual tools do you have for your system? 10s, 100s, 1000s? - or, for how many and what kind of questions don't you have contextual tools? and why is that? At the extreme, when practicing Moldable Development, we tend to address dozens of questions per day per developer through contextual tools :)
