Currently when using the "Grid + Details" view it only provides the ability to view the issue details in a panel to the right side of the structure view.

Many engineers however tend to use their screens in vertical mode and thus this side-by-side view is less than ideal as it gets cramped fast.

For these users, it would be really nice to have another option for "Grid + Details" layout where the issue details panel appears below the structure hierarchy panel rather than to the right.
