Implementing more and more touch events into "TosmE" by coding each separately got difficult. I thought about a touch-gesture-recognition module. A web search presented a lot of ready to use solutions.
That's no dead end, Dojo is ought to be extended. At last, I learned a lot about event driven coding instead of time cycles. There are other frameworks with much more features. This looks fine. iD is extendig to other frameworks to, we will see.
