[This is an automated message.]
This bug was filed before the changes to Bugzilla on 2011-10-16. Thus it
started right out as NEW without ever being explicitly confirmed. The bug is
changed to state NEEDINFO for this reason. To move this bug from NEEDINFO back
to NEW please check if the bug still persists with the 3.5.0 beta1 or beta2 prereleases.
Details on how to test the 3.5.0 beta1 can be found at:

Hello,

These enhancements have not been introduced in LibO 3.5.
Extension CorelPolyGUI (Improved trend lines) try to answer these questions but
is not integrated in LibO:

An enhancement request needs REALLY good reasons to be a MAB, liivhillar@gmail.com added this one without any reasoning. I remove and informed liivhillar@gmail.com by PM.

Any news about this bug?
Force intercept for trend line is a feature many requested if you search on Google...
