Simple as that.
The rulers are less important as we are facing a DPI dependant layouts, but a simple ability to use guides with snapping could help a few people from time to time, I guess.

I believe this might be what you want.
I’m not using github myself, so does this mean that the feature has been implemented and it’s coming in a future update?
Yes, it was branched into 4.7, so you’d see it there.
That’s great. Thanks for the info.
