Timeline Context - thicken Keyframe Size for Keyframes within a set frame threshold -

It's really either difficult or impossible to visually detect when a property has two keyframes that are a frame (or less than a frame) apart - and depending on the length of the timeline and its zoom level, even having 5 frames separation between keyframes is not humanly possible. Yet, this occurs more often than desired. 

And with the new Quick Offset feature this issue will hit more users as keyframes will occasionally lock themselves in-between frames. 

So, I'm looking at larger keyframe icons to depict such occurrences. It'll be great if the size can be responsive to timeline length+zoom levels. And add a threshold (in frames) for this to kick in with a default of 10 frames.
