Just tested it out, as you said one can add multiple locations but use the same location with multiple weather services, so thats nice.

What I don't like is that you need to swipe between the different locations to see their data instead of just having one page with the graphs one under another, but I guess that is personal preference.

Also there is just one widget that shows multiple locations and that only shows the whole day summary. If you add the hourly widget you cannot change location, it always uses the same one. But that seems like a simple thing to request from the dev, so I will do that.

Thanks again, closest to what I want!
