I think it would be outstanding if Oracle would provide a grid control with Apex. It could be one of the choice when choosing what kind of page to create (e.g. Tabular, Master-Detail, Grid). I don't know if any developers monitor this site, but how should I formally make the request?
BTW, the coolest grid control I've ever seen is called True DBgrid. I have nothing to do with that company or product. It's simply an amazing grid control. It makes any app sizzle.
Having a grid control like that from Apex would be outa this world.
