DrRacket Plugin Development

[James Yoo]

Hi all!

I'm an undergraduate TA for a Canadian university which uses DrRacket as its primary IDE for its introductory programming course. As a fun side project

to keep me busy during the summer, I was hoping to develop a DrRacket plugin which basically acts as an in-editor help desk. My vision for this is to

have a window that pops up once a user hovers over a function name that contains information from the help desk. I've already looked at the existing 

documentation for creating plugins, but it seems pretty esoteric. 

I was wondering if anyone has had any experience developing tools like this.

Thanks!
