On OS X you can use an AppleScript to launch the app then create a new doc based on your settings. I've used this approach extensively, though not to create new docs.
I haven't written AS in a while so I'll leave the complicated stuff to a more qualified person. But I can give you some example solutions.
- To launch the app or just activate it:
launch application "Adobe Illustrator"
- Direct AS to the file you want to open (like a template) with a path or a prompt like so:
set theDoc to choose file with prompt "Select the document"
- Then tell Illy to open the file:
tell application "Adobe Illustrator" to open theDoc
You can also set up some options to present in a prompt when the script is launched.
- Choose between opening various common template files without the prompt
- Create a new doc with the default settings
- Point the applescript to a javascript that steps in once the Finder interaction is over
- Activate a specific Workspace, depending on the project you're working on
- Synchronize settings with a server or Dropbox directory
Spending a little time setting up the script at the start can result in noticeable cumulative time savings.
