When I drag an item, or set the duration of items by dragging, on the timeline, I wish the lines would snap to whatever zoom scale is shown. e.g. years… months… days… hours… 15-min increments.
I never need minute/second detail when dragging. And, it’s difficult to get that detail correct, by dragging, anyway.
When I need/want minute/second precision, I figure that’s what the inspector panel is for.
For example, it’s frustrating to set a day duration for an item, drag it to a different day, and have the start be 23:50 the day before and the end be 23:50 on the day.
