Thanks Eric; yes I can offer a solution. The need to automatically move the start date on a Didn't Get To It Task and make it a First Thing Monday Task is similar (but opposite) to my As Soon As Impossible Blog post, in which I explained conceptually how to accellerate a Project Plan by setting the Planned Start Dates on Tasks that CAN start to their (earliest possible) Handoff Dates.. We have an AtApp that can do that now (UberCalc) plus a whole lot more that would fit the bill. And if you needed to preserve the original Planned Start Date, you could do so with a Baseline (annnnd our Create Baselime AtApp could do those automatically, on schedule, too).
With all that said, I do agree with Eric's points, and suggest that folks invest some time seeing how the out of the box Workfront features work first, and try to make them fit their needs.
Regards,
Doug
