Months ago, I tested Xara Online and found it really nice
although if we compare its features with desktop software
certainly feels limited... but maybe, just maybe, these
limitations are web browser limitations.

For example, in html files, layers could be implemented
as DIVs but within svg files, layers are implemented as
groups.

If my guess is correct, Xara Online will implement more
and more functionality as javascript code, so Xara Desktop
application would benefit from having (finally) a
user friendly programming language at its core.
