If the Vuo editor crashes, any already-running compositions continue to run. (You can quit them from the Dock, or if they don't appear in the Dock, you can quit them using Activity Monitor.)
This feature request proposes that, the next time you launch the Vuo editor, it would detect and offer to stop any compositions that are still running after a previous crash — more convenient than having to find them in Activity Monitor.
Allow the composition author to provide a custom Layer (or a group of Layers) for each component of each UI widget, to completely customize the visual appearance of UI widgets.
Proposed new nodes:
Make Action Button Theme (Layers) with the following Layer inputs:
Make Toggle Button Theme (Layers) with the following Layer inputs:
Checkbox: Toggled and Hovered
Make Slider Theme (Layers) with the following Layer inputs:
Active Track: Hovered
Inactive Track: Hovered
You could then create your own Layers (using Vuo's built-in Layer nodes, or using custom images) to feed in to these nodes, and the UI widgets would display the appropriate Layer(s) at the appropriate times.
