I have a small app that combines selected Finder items into a single PDF. I most often use this to merge multi page PDF's into a single file.
This app won't show up in the right click menu for selected (PDF) files. Of course I don't want to make this the default app for opening PDF's. All other PDF-related apps automatically show up in the context menu, but not this one.
What can I do to make this app show up in the right click menu?
