Regarding GUIs, I really miss a pure functional framework for doing so.
We all do, we all do. ;)
Currently I'm using Microsoft's WPF, and that is more or less declarative, a bit like BOOPSI or MUI on the good old Amiga days. But WPF has so many little quirks, not to mentioned a weakly typed XML-like language called "XAML". Still it offers the best experiences I had so far, because it is very composable.
What I would love is to build GUIs the Fruit/Yampa or maybe Reactive/Elerea way, using a graphical editor if possible. And allow separation of data (model and view-model) and looks (styling, CSS, themes...)
Oh and it should preferably make use of the GPU as much as possible, where it makes sense at least.
Anyway knows about such a framework in Haskell? It's a gigantic undertaking, but maybe if someone can make the basic framework, others in the community will develop controls for it?
I have concocted a tiny FRP library for my little wxHaskell project, which works quite nicely. Its main feature is that it can hook into any part of wxHaskell; thanks to higher-order functions, there is absolutely no need to duplicate the GUI API. In a sense, the point is that FRP is just a different way of talking about callback functions. It is by no means finished, though, and my project has currently hit a snag because wxHaskell's support for antialiased graphics routines is still in its infancy. No idea how to proceed yet.
