Allow Things quick entry with autofill
Airmail could allow to use the Things keyboard shortcut to create entry based on emails rather than the different (non-configurable) shortcut that Airmail offers (and that is not quick entry based). As described on this page http://support.culturedcode.com/customer/portal/articles/174723#capturing-links-and-text-with-autofill
The app needs to have an AppleScript interface so that Autofill can access a selection within it. Specifically, the developer needs to support linking to objects in the app via URLs: for example, Mail uses message:// and Safari uses http:// or https://. For text selections, the app only needs to use standard text fields.

I found a stand-in solution - go to system prefs>keyboard>shortcuts. Click on App Shortcuts then + and create a new shortcut for Airmail to send to things. The "Menu Title" input to use is "Things..." and just assign a shortcut! I used control+shift+space so it feels very similar to the actual default quick task autofill. Works like a charm!!
