- In the track view when Snap is active and smart grid is turned "off" the maximum resolution for the displayed vertical grid lines is 1/4 intervals. To be able to see smaller interval grid lines you have to enable smart grid but this is not really convenient as sometimes I would want to hold steady a resolution less than 1/4 and zoom in at the same time.
- Make the behavior of the "Snap to grid" in the track view the same as in the PRV view, so if I select a snap resolution less than 1/4 "with smart grid turned off" this will display only those grid lines at any zoom level.

One of those little improvements that would be good improvements.  +1

Don't forget to vote!   The right-side star, of course.
 
Just did myself since these seem usable.
