- New Objects (Flexbox, Graph, Treeview) - Pluginsystem to add/remove functionality - Reworked the entire Object system, instead of one big Object Class we have multiple classes: Object, VisualObject, ChangeableObject - Instead of one big Frame Class we have multiple Frame Classes: BaseFrame, Frame, MovableFrame, ScrollableFrame, MonitorFrame, Flexbox - Removed the Animation Object, and added a animation plugin instead - Removed the Graphic Object and merged it's functionality with the image object - Updated currently existing objects
