Sounds interesting, but I don't think it would work properly. That would 
mean that as soon as you start scrolling and more records are fetched, 
data may appear at random places in your view as the data gets sorted. 
Doesn't sound like acceptable behaviour. Or do I misunderstand something 
here?

That's actually exactly what happens now... For large SQL queries, where the default fetch (though I could never figure out how to change the default row count to fetch via the api)

If you use a sort filter, it will actually randomly pop up info as you say...

That's why I usually recommend you do the sort via the SQL...
