Each individual designer will have their own Custom tab with their own set of favorite control templates.
Control Template Types
There are two types of control templates that you can create in
– modifiable templates and read-only templates. In some cases may you want to publish a control template and allow them to be completely modified when used in other forms. These modifiable control templates are basically a starting point to a slightly or entirely different control at the discretion of the designer using it. Note that by changing the name of a control, you may break rules published with the control. In other cases, you may want to publish read-only control templates. A designer using a read-only control will not be able to remove nested controls nor change any properties that affect the underlying data binding (e.g., the name property). The designer can still change other UI-related properties such as styles and labels, and rearrange any nested controls on read-only templates.
