Hi, In the next development release you will find the following new features. Material highlight In the material editor there is now a checkbox that can be used to indicate tha the selected material should be highlighted in the preview window as well. This has currently been implemented as giving it a red colour, which will blend through the texture if one is present. This feature should help you to identify which material is applied where on the model. Non-modal editors Before the material editor, attached object editor, object information form and the object hierarchy form were modal. In simple words this meant they had to be closed again before you could continue working in the main window. I have now changed this and these forms can remain open while working in other places. This also means that these forms will automatically be updated when you load a new object. For example the material editor will then show the materials of the new object directly. Besides that also changes you make in those form, will be reflected directly in the main preview as well. So when you change a material to double sided for example, you will directly see so. I think this will make positioning attached objects or tuning material settings a lot easier.
