I have been trying to work with the Virtual Store, but it is very buggy and sparsely documented.

I would have expected a regular store instance could be swapped with a virtual store without complications, but unfortunately this is not the case. Many exceptions occur and strange behaviors when using sorting and grouping. Too much to turn into bug reports (you'll find two in the Bugs section though). I'm sure they'll show up when upgrading the kitchen sink examples to use this store.

Are you aware of this and (since at least you are now ) when can we expect a major bug-fix release on this?
