In Calendar, I can choose to view details for the day, week or month. A "working week" view would be appreciated. Ideally, the exact outcome could be specified (Monday-Friday or Tuesday-Saturday). Observed in 4:4.5~20100912.1174548-1maemo1.1173569.
The current snapshot version has a work-week and 3-day view, among others. Reachable for example via Actions -> Calendars -> "Work Week View" while looking at full week or month view.
Confirmed, version 4:4.5~20101013.1185418-1maemo1.1185177 .
