I've noticed that in 2017 the 'weight' so to speak, of corner or line-end snaps is way higher than the midpoints. What I mean is that in 2016, I could easily snap to either then end points or the midpoint equally, no matter how far zoomed out I was (within reason of course - able to see all three locations distinctly). However now in order to snap to a midpoint, I have to zoom in really far to get the cursor to not want to just snap to the endpoints.
This might seem like a little thing, but it really messes with my drawing workflow at times.
