1. I would like to hide a specific s-expression in the macro stepper. If 
I right click on a something, like letrec-values, and click 'hide' then 
all instances of letrec-values are hidden.

2. Going a step back takes a long time, I guess because the entire 
computation from beginning to end is re-computed? Can all the steps be 
cached along the way instead?
