Hi Terris,
Yes, we are working on this. To give you a little insight to our development plans and progress; We are putting the finishing touches to our next generation of applications which will certainly contain this important feature. The first application to come out of this stable is Stardraw Control, for which we won a recent Innovation award:

When this is completed, we will be releasing new versions of our applications based on this next generation of technology.
Now is the time and this forum is the place to suggest any other features that desire.
I look forward to your feedback.
