Apps that start to order everything by your preferences built up over time start to become possible and automatically repeating past uses. E.g. A new report completed and its 70% percent certain you move reports to a certain folder, it just happens.
Needs a lot of UI thought to be easy to override...
Anyway, I'd be interested to see how performant this is.
I like this quite a bit, although the similarity to SQL might pose more problems than it's worth in the long run.
That and AmazonML's striking similarity to Excel/CSV (not to mention the crop of ML-on-demand providers) show these types of interfaces and user experiences are a pretty glaring need right now in data science / ML / classification.
