I love the alignment and distribution tool for groups.

But sometimes I find myself wanting to center or distribute things relative to the borders of the map canvas itself.

Would it be possible to add a feature where we can center, relative to the canvas? Like an overall canvas layout tool. Could even be achieved if we could resize the group borders without affecting the scale/position of the objects inside, and align the group border to the edges of the map canvas.

I find that I wish for this feature when i make not-strictly-map maps. For example a "poster" that has a title and a framed map in the middle to make it look like a map poster you'd find in-game.

Right now we have to sort of measure it by eye, or by adding extra lines that are then removed.
