Can the graphics in MRO for the OSD & effects like smoke that are BMP format be switched to PNG? It would allow the graphics to be transparent without using the CPU opacity feature as the opacity can be used in PNG directly. Also PNG files are smaller in size so it would save some space and allow the game to run faster. I'm hoping it's possible as it would also all the graphics to be more detailed.
Below is an example of both formats in detail and size.
