I really like the plugin, the only thing that bugs me and that's why I am only giving 4 Stars, is the fact, that the icon names are nowhere explained and my support question hasn't been answered either.
I wanted to use custom icons and not they ones supplied with the plugin. It works fine, but its a bit of a guessing game for the icon names.
I went frequently to the site I installed the plugin on and each time we had some "new" weather conditions I found out, that another icon was missing.
For anybody else wondering about this, these are the names I have found out so far:
I might need some more comes winter...
