Thank you for the feedback.
At the moment we do not plan implementing this feature because it requires a huge refactoring of the control. This would introduce some breaking changes and we are doing our best to avoid such. However, you can follow the feedback item
in our portal, so you would be notified by email as soon as there is any change in the item's status.
In addition as another workaround to achieve this layout of the TileView (except the proposed solution in the blog post), you can check the approach suggested in this forum thread
and see if it will fit your scenario.
Thank you for the understanding.
