From reading the documentation, it seems possible to add a workflow as a fallback result, but I seem to be missing something.
In my case, I have created a nice little workflow that just takes whatever text I have entered, and appends it to a text file. Now, I can invoke this workflow by typing
log <my text>
which works fine.
But I'd like to avoid having to enter 'log' - ideally I'd just enter the text, and select the 'log' action, just like I do with e.g. Google search.
I thought I could set this up under Alfred Preferences -> Features ->
