Dear Xara...

Take three spaced squares and colour them RGB and Group.
Clone two copies.
Enable Smart Duplication (SD) for these and grow one left and one right.

Bug - Only the end two squares are duplicated, giving: <RGRGRGRGRG...RGB & RGB...GBGBGBGBGB>

A feature that can only count to two is dumb!

Ungroup RGB and Soft-Group.

Bug - The Smart Duplication button is shaded out.


Ungroup and move the middle box to a different layer.
Select RGB and Smart Duplicate.

Bug - The duplicated boxes remain in one layer, regardless of the original layer a box is on.

Place R, G & B randomly on the page.
With the Smart Duplication button enabled, select any two.
The SD spacing handles top-right & bottom right appear so you can drag right or down or even align top or left.

Bug - Selecting more than two and the CD button is again shaded.
Bug - Aligning top and the spacing handle disappears.
Bug - Aligning left and the spacing handle disappears.
Bug - Not offering a spacing handle on each edge is a pain.

Set R, G & B horizontally spaced.
Set R, G & B vertically spaced.
Offset one square in each RGB block.

Bug - The (+) is missing in the orthogonal direction.

Again, you have added a feature that is next to useless down to poor specification and implementation.
Where is your beta-testing?
