Comment 1 for bug 497641

I am affected by this issue as well. In my case, I need to center some text vertically between two guides and horizontally between two other guides. My idea was to create a manually sized text box, snapping its sides to the four guides, and then horizontally and vertically center the text in it. Horizontal centering works by just setting a centered alignment, but vertical centering is missing. Some complicated workarounds have been suggested on the IRC channel, but having this option would greatly simplify this layout task (which I would expect to be rather common)
