Wikipedia-URLs have always the same syntax. For example "http://en.wikipedia.org/wiki/London" or "http://de.wikipedia.org/wiki/Liste_der_Gem%C3%BCse".
It would be great, if this were implementet in the plugin, so that I only must choose the language per dropdown and then type the articles names - in my example: "London" or "Liste der Gemüse". Much simpler.
Next level: What about the option to compile a Collection of Articles by category and its subcategories? Would be really great.
