Use less technical terms:

• QML Type -> Component (or Component Type)
• QML ID -> ID (or Component ID)
• QML Properties -> Properties (or Component Properties)
• Add Imports -> Add Preset Components

I'm not sure about the last. We are going to try to hide "imports" from QDS, too, but I think you might have to use it here. However, the chosen term for different QML modules is "Preset components", so that is what they will be called in the Library in QDS 2.1.
