Show Timeline vertically

Hi,
I really like the timeline and calendar functionality. I am on 8.3 from about a year ago.

One main 'obstacle': one of my potential customers is very critical on the current timeline being shown horizontally, they want to see the timeline vertically.

So the lanes are shown as columns and the time is shown vertically.

This visualization seems more efficient from a space-point of view, each line in the calendar takes less space.

Is this possible with my version of Smartclient or available in a newer version?

Thanks!

gr. Martin
