I've been playing around with beta 4 - this setup is working well for me:
My Today plugins are:
- * phoneAlarm
* Spb Mobile Shell
* WeatherPanel
* WP-Pilot
Spb Mobile Shell is optioned to "Auto-hide the tab content". That way, WeatherPanel is visible when the tab content is not - WP-Pilot works like normal.
To get this to work, I did have to decrease the height of the Son-of-Commuter-240-QVGA layouts a little to 123 pixels. I'll post that update tomorrow.
Oh yea - I switched back to Wisbar Lite (from Wisbar Advance 2). I still prefer cascading menus...
