I was approached about making the smallest window size for Luppp smaller, so it would fit on the OpenPandora screen:
The size this can manage is 800x450: that's smaller than all netbooks I know of... so going with 800x450 you've got all bases covered!

I'd argue everything should be visible: tabbed UI / expanders can be used to maximise pixels usage.

Its tabbed / expanders are *not* and ideal workflow
