App demo examples

I would like to design ScriptCase allow applications like this.
DEMO

I think SC needs a designer sheets where you can drag and drop. grids, buttons, menus. So that we have a better design in our applications and look better than a single grid.

App opinion that you would like to develop with SC and need app to make more complete.

I think SC team need fix your examples or demos. for example when i run your demo in your site online shop it do not works correctly.
i would like you test to buy a product.

So your demos in our SC enviroment have same problem.
