I haven't seen it mentioned anywhere, but I really wonder why the contact shortcuts on the N97 doesn't have the same functionality as on the 5800 - a log of calls and messages, when you press on one of the four contacts.
On the N97 it's just a plain shortcut to the address book.
The idea on the 5800 is brilliant, but the way, it is executed, it is not that good. You have to choose either the contact plugin, or your calender, music shotcuts, and apps shortcuts... I have to have my calender on my homescreen.
I had really high hopes that Nokia would have combined the two things, now that we can choose freely what we want to see on the homescreen. I can't see why the contacts can't expand up, or down, over the other widgets, and display a log of calls and messages. We can have eight contacts on the N97, but only shortcuts to the address book, which, in my oppinion, is a waste of space, on the homescreen.
Personaly I have choosed my four favorite contacts, and removed the widget again. Now I have my favorites starred, and moved to the top, in the address book.
I hope that Nokia will implement it in future firmwares, but I have my doubts, when it's not already there by now.
