@Chris, sorry my 'Alt+Select' is hold down the Left Alt key while dragging the rightmost middle control with the Left Select mouse down for the FlexGroup.
Only needed is Smart transform is Off, which is the way I always work to preserve my sanity. I didn't say anything about left aligning the Variant.

Not essential for the bottom middle control of the Web Block but again it maintains a consistency my muscle memory can accommodate.

Left Align is essential for a full-sized image as it does its own thing if Centre or Right Aligned.

It should not be the case that making an image too big throws so much off, hence my barb at Xara.
