Sooner or later it will be necessary to create a QML UI for gPodder if it is to integrate nicely with devices on which Qt is the "native" toolkit for third party apps. At the moment, the reusable UI elements that can be used with QML (Qt Components) have not yet been officially released (the Git repository is available on Gitorious, though), and there are no UI style guidelines for Harmattan out (yet?). I'm also not able to locate UI style guidelines for QML apps on Symbian^3, and there are only a few small sample QML apps out right now.
Let's look at what we have on Maemo 5 right now. Here's a simplified overview of the current Maemo 5 UI of gPodder:
You can also check out the full-size image (~ 3.5 MB).
The UI follows the Maemo 5 Style Guide where it makes sense and tries to come up with better solutions where the Style Guide does not have a definitive answer. I'd like to hear your opinion about the current UX of gPodder and how these concepts can be translated into a QML app that integrates nicely with "future" UIs (Harmattan, S^3). The new-style episode list that can be seen in this picture will be made available with the next release that will be out Really Soon Now™.
