The very first thing I noticed when I started to "play" with the bug was that swing library was missing. After a couple of month I just accepted AWT is the best I could do. But a few weeks ago started to see the light at the end of the tunnel thanks to LWUITMB. LWUTMB is a port of LWUIT on top the MicroBackend Library.
With some modification I was able to import LWUITMB into the Bug-platform, and even wrote some apps (SimpleLWUITSample, AccelerometerVisualizer ). LWUITMB-BUG is far from stable and there are some limitations, the scrollbar doesn't work properly nor the animation features to name some. Nevertheless, I think LWUITMB is a great library for the bug -platform.
I'll keep playing with this library and keep you update.
