Hi Charlie,
Thanks again for the suggestions.
1. We'll add that in a future version. It's already on our plan board...
2,3. These features are only useful when the flex is still a perfect straight or a perfect curve. If you don't use the control points after using the 'Adjust flex' functions, the old values will reappear in the dialog box. If you've moved them, there are no correct values to put in the dialog box, so the default will be shown. Any suggestions here to make it better are welcome!
4. Usually, you'll find the information about the point in the status bar at the bottom of the screen. Here, normally the information taken from the catalogue is shown. To avoid confusion, we do not really want to add more details there as we learned that that usually leads to more questions than answers

Hope this helps a bit.
David.
