For the next version of gPodder, I plan to have a better suited user interface for the tablets. For this, I needed a finger-scrolling replacement of GTK+'s ScrolledWindow. libmokoui2 provides just that, and it's now available in Diablo Extras.
The package is based on Ubuntu's libmokoui2 source package, but I have removed the doc package and the Vala bindings, because you can read the docs on your computer or online, and I didn't want to mess with Vala (yet).
It also did not build on Chinook, maybe someone can have a look at the build logs? It's working fine on Diablo, though. Example code in Python is also available.
