Clusters allow you access to the decorations inside the cluster but you can also drop decorations on a custom .ctl file too but there is not way to programmatically access them.
Make any custom control you want, I used a string. Plop a decoration in the .ctrl file and use in a vi.
Then try to get a reference to that decoration. I don't see how the traverse would find it unless its in the Vi server hierarchy. I've tried tagged objects etc. The decoration refs need to be on the control class like the cluster class is what I was intending to say.
Note that even though you can resize the decorations, you can't individually select them. As a result, Resize Objects doesn't work on decorations in a control... That could be considered a bug.
It's a corner case (not many will run into this), and a fix is probably quite hard to implement. So +1 for me, but I wouldn't wait for a solution.
