Reverse bottom arrow in clean filter image

[xifedI]

In figure 8-2 all arrows point left to right:

But in figure 8-3 not all arrows point right to left:

The bottom arrow in figure 8-3 should also point right to left, because the files are staged.

Unfortunately, I can't change this picture myself, because I don't have a Mac nor Sketch 3. 😕

I just noticed this too, I think the fileC.rb arrow in the diagram should be pointing right-to-left.

Unfortunately, I'm not able to edit the source file because:

1. It is in a binary, proprietary format.
   1. The file is actually a zip archive, so I unzipped it.
   2. I greped for fileC and found a JSON document. I opened the document and could not quickly determine how an arrow is made near fileC.
   3. I greped for arrow and found other JSON documents. I could not quickly determine how these arrows might be related to fileC.
   4. That format does not look like it is intended to be edited by humans.
2. The corresponding editor program is commercial/non-free and OSX only, but I don't have OSX.
3. I can find no alternative open source programs for the format.
