• The salvage corvettes being shot down by interceptors should be made more obvious.

• The remastered's orbital bombardment and radio chatter before the end of the video has better timing. Perhaps we could update the NIS to touch this up.

• The font scale of the recording timer is very small on larger resolutions. Consider upscaling it variably and move it closer to the center of the screen for a more cinematic feel.

Leave this to KAS modding... somehow. And work on the APIs that make singleplayer KAS files moddable.
