Guess I’ll have to be keeping up with “the internet”. Buienradar.nl changed their page today and that stopped the widget from loading the image of the current rainfall correctly.
Furthermore I thought that I had put saving and retrieving of preferences for size and source in the last release. It however happened to be only in my own development version.
Nevertheless, it all works now, including the preferences, please don’t hate me for updating it so quickly (blame Buienradar.nl!) and stay dry!
