Can one do FRP with Haskell connected to Javascript in the browser? I
believe there is a standalone version of Javascript.

This isn't really a specific application, but what I'd like to see most from FRP is an example of something that involves moving between windows and dialog boxes. All of the GUI-based FRP examples I've seen so far involve interactions in a specific GUI layout. It's unclear to me how FRP extends into a situation like:
- There's a starting window showing several options for what to do - When the user chooses an option, that window closes, and a new one opens with that activity. - In response to some actions, dialog boxes appear with their own interactions.
It's not clear to me if anyone in FRP has an idea of how stuff like this fits in. Is there some FRP trick to handle this declaratively? Or would you just say each move to a new window ends or pauses one network of events and behaviors, and starts a new one?
That's a very good example. Unfortunately, I am one of those who don't have any idea of how stuff like this fits in. :)
I think it's possible to get something like this with pausing and resuming event networks, but a general and elegant formulation would probably rely on dynamic event switching, which I haven't attempted to implement yet. I'm trying to pick the low hanging fruit first.
