Facebook keeps at it, with another update for their Origami plugin.
I think that for Retina display users, this is a really useful addition. Many long time QC users probably already know how to do things that they are attempting to make easier via various extra patches, and I would recommend to use stock patches still whenever possible. I personally find the "editor mods" more useful than any of the virtual patches, or built in patches (like the Layer Group patch redundancy with Render In Image, for instance, because they feel like "Render In Image" sounds weird.)
Of note is the fact that you can still use this editor add on with the most recent kinemecore, and in fact, kinemecore is on all QC installs at Facebook.
