So opening up the NWjs plugin i found out that the file dropped variable isn't a array so it will always show the last file. By changing var droppedfile to an array and little more code it works like a charm.
But I really don't like to change the official plugins, feel like i'm braking rules.. such a bad boy.. :)
Is there a official place to ask for changes or just post it here on the forum and hope for the best?
