I don't know if anyone has thought this before, so, I'm sorry if that's all said.
Since you can make walls transparent it could be possible to make windows transparent. Other mods that try to hide the opacity of windows adding reflections said that you'll need to change the model of ships to make windows transparent, but since you've already done that, making walls opac and adding a kind of semitransparent layer to windows, it could be possible to see trough them!
This combined with reflections will be so awesome, I know it's a 'not today' idea, but when things get ended in the IVA department, it could be a great thing to add.
Thanks for the mod, it's amazing what you have done!
