It doesn't surprise me when a code base is retired. There are strategic considerations here so that M/S can use the same code base to support web based and smart phone and tablet markets. What this does is allow a higher user predictability of what they will see when using this app on the different platforms. It also allows a smaller support footprint and a coherent upgrade cycle.
On the downside, it means M/S will not be taking advantage of the protocols only found on the PC and not on Android or the Ipad/Iphone devices or vice versa. In other words, the capabilities will only be those found on all the systems that use this application.
That being said, this application has been woefully undertested and poorly conceived. The effort needed to balance the numbers between the transactions and the Portfolio Holdings tab's Number of shares has been huge. Sorting / Reordering wasn't working for much of the time, and Date sorting of transactions still isn't working.
A common task: review all transactions for an equity in chronological order, as for tax purposes. This isn't possible now.
The project manager and most of the software developers have very little idea of what a portfolio manager is used for. Where are annualized numbers? Where is the amount of the dividend? Where is the flexibility to choose columns?
I've been using PM since 1997 and have about 3000 transactions that migrated over. I won't be reentering them all, but my goal for now is to migrate everything over, choose a future home for my portfolio management, and always enter all future data in excel as well as the selected portfolio manager.
