Progress

After scrapping my previous content browser (a pop up window to add content to the scene) I started working on a simple tree type of list with resources.  Basically there is a list of folders that can not be changed or deleted ("Models", "Levels", "Scripts", etc.) and in these folders you can import the respective content.  So, if you right click the models folder you can import models.  Then when those models are imported you can simply double click the model and it gets added to the scene.  All of this may not seem like a major advance but it is definitely better then the previous content browser.  I also started working on a prefab system along with scripting!  I didn't actually start the scripting itself, only the general editing and use of scripts in the editor.  However, I am going to start the scripting language soon.  Probably be better to get that working before I progress further into the engine.  Hopefully, by next week I will have a well thought out design of the scripting language.
