Hattrick

I'd like to expand a workflow snippet, but only if certain apps are focused (just like the "Hotkey is only active if the following apps have focus" option for hotkeys). My use case is that I have a note editor for which every time I begin to type a link (which is in the form of `[[link here]]`), my workflow will pop up and offer suggestions to complete the link. I can't redefine the link syntax, so I'm stuck with "[[" as the snippet trigger, but as my autocomplete workflow is only for this app, I only want the workflow to trigger when my note-taking app is active.
 
(It's true that I could use a hotkey instead of a snippet trigger, but then this would no longer be an auto-complete workflow. Moreover, different link types can't be handled separately with only a single hotkey, and the number of hotkeys will multiply quickly. Separate snippets for each link type would handle this easily.)

You can do it by changing Application to Custom in Alfred Preferences → Features → Terminal and setting the code to something like
on alfred_script(q) tell application "Terminal" activate do script q quit end tell end alfred_script That’s a start but isn’t it, as that will try to close it too soon.
 
For running one-offs, I recommend RunCommand instead (disclaimer: I’m the author). It will run the commands without opening a Terminal.
