I used it to easier see where days start and end.
But in new version it seems to be gone.
Is there a new way of doing this now ?
This bug should be fixed now in build 7.5.8329.
See the sandbox:
Noticed that this is still an issue if Im viewing 24 hours on a day.
23 hours I still see the vertical break but those divs are not there when showing 24hours.
Here is an image showing 24 hours and 23 hours.
