Maybe there is something already.. my designer is failing to load data trough direct proxy unfortunately (although configured properly and works in browser) even the load data menu is grayed out.
But I have this question: Isn't it going to be useful if designer gives you option to convert loaded data into model entries that you can just edit later. Sometimes I pull very large data rows from sql, I spend time designing the database.. why should I spend more time into typing all those column names in designer. This should be fairly ease to do.
As i said.. maybe is already there... Cannot say for sure.. direct store does not even try to load data.
