I have that one. But only 1 weather slot allows the icon to change. I need the weather slots to allow my weatherberry and meterberry icons to change....

You can use two apps via slots 17 & 18 (i.e. instead of Manage Connections) or ask Vince if he'll Mod it for you. I normally use MeterBerry & BerryWeather and they both update fine.
Or dl the source files for v2.1 and mod it yourself...
