The script was submited do SSC a few weeks before it was published.

In the mean time I managed to implement it in a real world application and the results are good.

Maintaining the tags and registers tables proved to be a challenge as well.

The final version comes with options to

server-side paging (essential for web applications),

more filters, aggregations and order by options.

Thanks for everyone giving it a good rating.
