One of the big problems we always have is that different users want to see different part of the data and they hate to filter and slice it every single time. Only other workaround is to create a separate report for each user which is very bad idea even if your customers are VPs. IT would be great if each user could slice, filter and save those settings as default for their view. Even if actual file gets refreshed, these settings would be preserved as long as the underlying object is there. Many, many BI solution developers and their users would be very happy with this capability.
