https://doc.qt.io/qtdesignstudio/qtbridge-xd-using.html#annotate-layers-for-export says, "In the Component field, specify the component... to morph this layer into."

This requires the designer to know the exact QML types and type them correctly. Arguably, the designer shouldn't need to know anything about QML.

Furthermore, this process must be manually applied to each morphable component in the project, which is time-consuming.

Suggestions

1. Instead of a free text field, provide a combobox that lists all the supported types a shape can morph into.
2. Provide a mechanism to mass-apply morphing info onto multiple shapes/layers.
3. Provide a mechanism to intelligently auto-select the morph type based on the XD shape/layer (e.g. if it's an SVG "rect", then the most obvious candidate is a QML Rectangle)
