1. Make sure to select a texture gamma for the default Bitmap node. Currently it can only be selected from the File I/O dialog to select a texture. You should be able to set it at the Bitmap node level.
2. Right-click in the Slate Material Editor to access the map. I want to access this function via the keyboard. Simply create a shortcut to search by name
3. Should I always load Scene Materials from Material/Map Broeser? It might be nice to be the default, but it's heavy. I need the ability to turn it off.
