Version: Alfred 2.1.1 (227) on Mavericks 10.9 (13A603)
I hit the trigger key and type, say "Textual" and hit Return. Instead of launching/focussing Textual, I'm prompted for a document to open. In the case of Textual, there are no documents available, but when I hit enter again, instead of opening Textual, nothing happens.
If I do something similar with pages, where I have some recently viewed documents, then I can select one and hitting Return will happily open the app.
After some experimentation and swearing, I worked out that, if I want the old behaviour, I can do <trigger> "Textual" <shift-Return>, but that's not really an adequate solution, especially as that's not how Alfred is documented as working.
If this is supposed to be the new Right Way, then fine, but please supply a preference setting for old stick in the muds like me who want the old behaviour.
