Issues: Not intuitive GUI element placement
‘Set’ button of the ‘Object Properties’ panel is placed high up, next to the ID text‐entry box, suggesting it is applied only to the ID box. In reality, ‘Set’ button applies the changes for every text field.
Position the 'Set' button to lower right corner of the panel. The button should probably be positioned under the 'Interactivity' rollout.
Rethink the 'Interactivity' implementation in GUI. A simple improvement would be a dedicated tab for 'Interactivity' on the 'Object properties' panel.
