Hey monkeys,
I started to add undo/redo support to jMPThe jMonkeyPlatform, a full-fledged IDE with plugins for editing jME3 content and assets. Integral part of the jME3 SDK., almost all of the properties in the SceneExplorer and most things you can do in SceneComposerA plugin in the jMonkeyEngine3 SDK, allows editing the content of j3o files which represent a complete scene or model. should now be undo/redo enabled, please test the system and report back here. All plugin developers can check out how to add undo/redo to their plugins in the wiki, its really easy, let me tell you that much 
Known Issues:
The undo/redo buttons are not enabled when the Properties window is active, only when SceneComposerA plugin in the jMonkeyEngine3 SDK, allows editing the content of j3o files which represent a complete scene or model., SceneExplorer or SceneViewerThe main 3d window of the jMonkeyPlatform, displays the output of different plugins like for example the SceneComposerA plugin in the jMonkeyEngine3 SDK, allows editing the content of j3o files which represent a complete scene or model.. are.
