I was browsing the Mac App Store last night looking for Apps which have photos extensions (which is not an easy task) and I came across a very interesting app which immediately got me very excited. The app, which is a basically just a photos edit extension is called “External Editors for Photos” and it does exactly what it says in the title. It addresses one of the biggest shortcomings of Apple’s Photos by giving it the ability to use any image editing application as an external editor.
