Does not work well with Files APIs

Creating a new file in Drive via Files, opening-in-place, and saving to Drive via Files work not at all or very unreliably.

I need to ability to create new files in Drive, editing existing files to drive, and save files to Drive, all using the standard system Files interface—not Drive’s weird proprietary thing, which few apps support anyway.

But to name just two problems I am not able to open an OmniOutliner document from OmniOutliner that is stored on Google Drive, and attempting to create a new document on Drive via IA Writer or Textor or Pages just fails with a message about a missing helper application.

The Files system makes the iPad nearly as capable as a desktop computer when it comes to file organization, and grouping data from different applications together, but only if third-party storage providers properly use it.

As it stands the most-capable and least-buggy options are Dropbox and iCloud Drive.
