Not wanting to turn XaraX into bloat-ware, here are my two suggestions for simple enhancements that would allow me to use it more often:

1) Text handling - if you added Tab Stops, for example, I could throw away Corel Draw

2) Connectors - if you added connectors, especially smart ones which re-route when an object is moved, I could throw away Visio

(And I agree with the previous poster, !Impression was fantastic)
