Before, workflows happened outside of computers, so integration was not required. The computer was a tool used in specific part of those workflows, and each app was discrete. Now we have lots of thing happening digitally and often whole workflows start and end on the computer. Data processing should be continuous and not discrete steps. A good solution I've seen is the File provider API [1]. One example is Working Copy. Each repository you clone is available from the Files app. An app like Textastic can then link a folder or a file to its working space. But so many apps (PDF Experts) are reluctant to add that (local files, not online storage).
