I made a slight mistake in my MrReaderURL workflow description. I said to set the service in Mr. Reader up as:

editorial://?input=[URL]&command=MrReaderURL

While that did work in my initial tests, I forgot to encode the URL. It should be this:

editorial://?input={[URL]}&command=MrReaderURL

With the curly brackets around [URL]. Sorry about that, if anybody is or has tried using it. Basically the workflow just gets the url of an article in Mr. Reader as I out and opens it in Editorial's in-app browser, so you can link it in something you're writing, or use other workflows such as the ClipWebpage workflow. Cheers!
