THTMListBox improvement request

It would be very helpful if there was an 'autoscroll' property to make the Add method more useable. I have just about managed to make it work by calling a function to set the topindex property after each Add call, but only because my application only adds one HTML text line at a time. It becomes a bit messy to allow it to support resizing the field and changing monitors/DPI, and even then there is no integralheight property so the appearance can be less than perfect. An enhancement to this component would be much appreciated.

I'm not sure I fully understand. Does it need to do more than ensure that new added items in the list are visible?
