A nice-looking concept, but it doesn't appear ready for release.
Documentation says that when you double-click on an object, the object will open in the appropriate application. I couldn't get that to work with a text object copied from AppleWorks. Double-clicking did nothing. It didn't open in anything.
I couldn't get the text resize buttons to do anything, nor the transparency buttons. And when I click on the grid button, it both toggles the grid and opens the preferences pane.
The comments option is apparently intended as a label for an object but it only works when hovering over the object. For a text link or a URL, you also can't see the contents unless you hover. So you have a collection of objects with no clue what each one contains until you hover over it. Yet the documentation appears to show that each object is labeled on the panel.
I can't recomment iXiu at this point.
