Whoa...did I miss the stealth week view in the release notes? I clicked on the week number on the left in the Month view, and I get a (Palm/Outlook)-style 2-column week view! This is great! It's not really highlighted in the release notes, or maybe I just glossed over it...
I'm thrilled just to have it, but now that I'm using it, it would probably work better as a first-class view (like day, workweek, month) with its own icon. Switching back-and-forth from month-view-in-month-mode and month-view-in-week-mode is cumbersome. When I hit the "month view" button and context-switch from some other mode (journal entry etc) I don't expect to see only a week's worth of events. Plus the navigation metaphor is broken: the "<" and ">" buttons on top of the view take you to the next <b>month</b>, so from the week beginning Feb14 I get to the week beginning Mar 14. Whereas the same buttons on the window toolbar go to next week and next month. It's unintuitive and confusing.
While some people may find navigating to this-week-in-next-month useful, the most likely thing for a user to want to see is the next week and there's no button to do that. In that sense there should be 3 buttons in week mode: ">" (next week), ">>" (next month) and ">>>" (next year).
So I'm lobbying for 1) making it an independent view with a button on top, and 2) allowing the user to select which buttons appear on the toolbar, since they already run out of room in portrait mode on my C860. I never use the journal & list view buttons, for instance, which would allow me to see the navigation buttons without having to click through to the continuation dropdown menu.
Also in the suggestions category, I find the "dashed line" for the half-hour demarcation in the Week view a little disorienting/distracting. (I'm an advocate for Tufte-style visual minimalism in UI design). What would be nice is to have an option to set the line color, weight & style for the main grid and the 1/2 hour lines. (Since you're presumably just setting Qt::PenStyle anyway to get the dashed lines this shouldn't be particularly burdensome.)
