There is something I mentioned in the past, many Xara versions ago, but still it isn't possible, don't know why such limitation.

In any program I can make an image of any size, but if I want to make a 28x28 or a 5x5 image at Xara, I cannot, because the minimum size is 48x48 ...
I know I can word around with clip view and such, but why do I have to spend the extra time with workarounds instead of straight setting the size I want?
