A very, very, long time ago Andreas & I had Words about this matter. When I first wrote the event sensor stuff I left it as very Morphic related, which seemed reasonable at the time for a prototype. Andreas correctly, albeit rudely, pointed out that the basic mechanism should not tie to Morphic or indeed any other specific UI layer. I think we eventually worked that part out ok.

One might argue that EventSensor and a few other classes should be moved into a category other than Kernel-Processes on grounds of not being really wanted for some postulated totally headless image.

Thinking about this reminds me that it might be a good idea to merge in the keyboard state tracking that I made for NuScratch. Internalised into EventSensor might simplify it; and perhaps it is a good model for replacing the messy #peekButtons etc.
