The developers would like to have the ability not only to select the components to load but also the features at the point of starting (especially for heavy components like the Grid and TreeView).

For example, they would like to be able to load single features instead of all functionalities.

The goal is to have lighter output, meaning that the whole script will be less KB in size and it will load faster. This will save loading time and in turn less bandwidth will be used which will make the cost that development companies pay to hosting providers smaller.
