BIDS Helper available on CodePlex

Furmanng posted a set of utilities to CodePlex that help your OLAP development called BidsHelper.

The features are directly integrated into BI Development Studio in toolbars and menus inside the Analysis Services designers.   It currently has an aggregation manager, calc helpers, MDX Script deployment utility, dimension health utility, plus many more features.  Even if you weren't interested in the specific features Furmangg put together, it's worth checking out to see how he was able to integrate at that level.

 So, check it out!
