Another idea: if I allow the list of objects in the panel to be infinite,
Sorry, but I'm having difficulty figuring out where you'd get an infinite list of objects to put in the panel. I suspect any solution is going to depend on how the list of objects is put together.
It could be any lazy list, potentially infinite (and I would not like to evaluate it). An example is a "find" function, wich returns a lazy list with the use of unsafeInterleaveIO. It would be useful to see the actual first N files as objects into the "panel" or desktop area, or list, anything visual, and then be able to obtain, for example, the filtered list of all the "sound files", which would still be a lazy list. Should the user scroll the panel down with some arrow-like control, the list would get evaluated and the find function would run under control of the user interface. I am just thinking about what a "lazy functional desktop environment" could mean, trying to figure out some use case.
