With introduction of customised margins in Mathcad Prime 6.0, PTC finally convinced me to make the jump from Mathcad 15. However, another version release (Prime 7.0) and I still cannot write up my calculations as a complete report inside Prime, as a large majority of users did with Mathcad 15.
The reason for this is the inability to have a different header / footer for the first page i.e. to make a tile page for the report. This was basic stuff back in the early double digit versions of Mathcad. Don't get me wrong, Mathcad had its challenges when trying to present a formatted report, and PTC have gone a long way to correcting some of these issues with each revision. Give me a option to change the first page header/footer and we almost have a software with the presentation functionality of Word and calculation power of Mathcad Prime (isn't that what most people want?).
