All scenes and objects in your project have general and object specific settings. The settings panel for each object will be visible to the right in Yooba Studio when the object is selected. In the image to the right a background scene is selected, and this has only one settings panel.

By clicking the arrow to the right of the panel title, you can collapse it. This will affect this specific panel everywhere in Yooba Studio until you expand it again. Many settings panels have sub-panels that work in the same way.

The panels can either be set to have one opened at a time ("Single") or you can open and close the panels manually ('Multiple'). This setting is available at the bottom of the settings panel area. 

You can Control-click panels to have more than one open temporarily, even when in 'Single' mode.

If you add effects to an object, every effect will have a new and unique settings panel.

When multiple objects are selected, only the panels they have in common will be visible.
