As stated by @ndavis in D22617#499767, document icons should have the corner fold in the top-right rather than in the bottom-right. Reason is that we usually add emblems to the bottom-right. In D22617 I started with snap-page, but there are many more icons wich still have the corner fold in the bottom-right. In D22617#500168 I started a list of them.
Will work on this be appreciated?
[ ] Move corner fold to the top-right for existing icons.
[ ] Leave a note in the HIG that important icon details shouldn’t be in the bottom-right, with the document corner fold as example.
