If I understand you correctly you can't currently make alfred fallback to actually triggering one workflow with inline results without selecting it from a list with one item. Couldn't you make it so that if there is only one fallback it can be auto selected? My goal was to make alfred behave as similar to the chrome adressbar as possible. It would be even cooler if it mixed my chrome history into the results also, but that seams much more complicated. Unless perhaps chrome offers an api to get the same results as the chrome adressbar..?
Is there a bug tracker where I can add a feature request?
Btw, I think I rather have inline results than suggestions. So I guess having this workflow as the fallback: http://www.alfredforum.com/topic/940-google-search-in-line-results-workflow/
