Service Station is a modern macOS Finder Extension that lets you customize the Finder's right-click menu. On the Mac App Store. Add your favourite applications for any file type. Or run scripts directly from Finder.
This looks really cool. It's a little less powerful than I first though (i.e. able to completely edit the right-click menu), but given that it works through the Apple-supported Services pathway, means that it's less likely to cause problems, as some other extensions do that use private APIs, and yet still usefully allows you to tweak open and working with file types.
