The component ID is the name used in the internal editor code base. This name is also used when tracking BI events.

The preset name is the elements's section name in the add panel.

The element name is the general name in the system. This name displays in the tag of the bounding box. It is also the elements name in the layers panel, in hidden items, search results, and when arranging overlapping elements from right click.

The Corvid element ID displays on the component bounding in dev mode and also in the properties panel. This ID is customizable to the user, and is what they will use while writing custom code in the system.

Category - The category is the first, main column of the add panel. These categories are more general, and the element will likely be added to one that already exists.
Sub Category - The sub category is the specific name for your item. This will typically be the same as your preset name (although sometimes there are exceptions).

This name is the element's section name.

Each preset name has an information icon, which opens a description tooltip. This description always has text, but can also display an image or video.

Element's have a visual display in the add panel, called a preset. Depending on the technology of the components, these presets will display linked to the template's theme, as studio designs, or in a static display (we use this for vertical's typically). 

When presets are a mix of different layouts, they sometimes include a textual description on hover. You can see an example of this in the Gallery category.

Elements are added to stage in two ways, they can be dragged or clicked. Depending on the element, there should be definitions made for its default location on stage.

*It may also be relevant to indicate the items Z order when added to stage.

Each element should have a defined width and height as it is added to stage.

Once added to stage, the final design display is dependent on the environment in which the element is built.

In cases where elements are a bit more complex for basic users, there can be a first time popup which provides additional information about the experience.
