Dear Xara...

...I find the Locking option you have introduced to be next to unworkable.

At the lowest level, you have to go to the Page & Layer view and somehow determine when the locked item is as Locate clearly cannot be invoked.
The sanest approach to unlock a locked item would be to have a meta-key combo plus a right-click Select (Ctrl+Right-Click).

What is also bad is if you Group or Soft-Group two or more items any subsequent lock of one of them still allows the group to be selected and then the locked item can be manipulated, negating the whole concept of locking position, scaling, skewing or rotating the locked item.

I currently soft-group a small under-shape with the locked item to be able to access the Lock context menu or manipulate the locked shape.
This at least stops an accidental selection as the under-shape or the whole group has to be selected.
I can then also Locate the group in the P&L gallery.

In my mind, a locked shape also ought not have its position on its layer altered.
Using the grouped approach, I can Ctrl+Unselect the unlocked item to then manipulate the order of the locked item.
