Cleaner Interface: Panel spacing has been refreshed so it looks less cramped and is easier to navigate.
Grouped MultiDriven Entries: Linked targets are now neatly grouped under a single named panel driver instead of cluttering the UI.
Flow Improvements: Added Sensitivity and Target Delay features to the Flow nodes/effectors for easier cascading animations.
Exclusive to the Pro Version
Delay Effector Mode: Adds a dedicated waiting period before driven values start to respond.
