Would it be possible to have users (or as a temporary solution only the administrator for the whole system) set a few thing that might fit a particular organisation:
1) in the overview, how many documents, notes, etc. are shown upon first display
2) turn on/of to show items from sub-workspaces if you are not in a particular subspace (because right now, if you are in a higher lever workspace, you get way to much information which is confusing if you don't already know what you are looking for
3) default calendar display (which is not necessarily the last used display), i.e. month, day or week view)
4) new option, and should also be part of 3): view calendar as a list, so it is easier to get a long term view of activities.
