Yeah, we used to show "minor" gridlines representing the next smaller unit than the current scale. These would fade out if the timeline was compressed such that they were too close together. We have a request to add those back in our database and we'll put down another vote. It's nice to know you miss that - I enjoyed implementing it the last time around.

Experiment with holding down modifier keys while you drag. I'm out of the office on an iPad so I can't test which does what, let alone recall, but shift or perhaps option will cause the drag to "snap" to the granularity you're looking for.
