New Component Wizard
This wizard is invoked when you use Add Component in an AssemblyLine or when you use from the main menu bar.
When you create a new component in the Resources folder you will have a slightly different wizard layout. For a new connector, for example, the wizard looks like this:

The component name will be used as the suggested file name in the folder; it is advisable to change that name into something meaningful.
When you create a new component in an AssemblyLine, you will have many more options in this wizard.
The first page of the wizard is the component type selection page. In this page you choose the component type you want to add or create. The left side contains a list of filters that will select relevant components based on the label in the list.

You can filter the contents by typing in the Search field. As you type, the list will be matched against what you have typed in the search field (case insensitive contains match).

At this point you can choose to finish the wizard and the component is inserted into your AssemblyLine.
When you choose a connector you will be presented with a series of forms to properly define the connector. For all other types you can only finish the wizard and configure the component in the AssemblyLine.
After selecting the type you are presented with the Connector configuration panel.

See also Connector Configuration form characteristics for some specifics in completing this type of form.
The next step will show the Parser configuration if the connector can use one.

Use the Select Parser button to choose the parser for the component:

You can remove the current parser from the component by selecting the "(Remove)" option.
