1. First person view angle of sailor resting on the bed (for better immersion experience)

2. the interior looking more old and worn-out ( the current interior feels like everything is brand new)

3. more food storage in the corridor of (e.g. torpedo room, crew compartment), sausages hanged on the ceiling

4. the hanging metallic chain should swing too

5. yellow light instead of white light for someone who like the yellow light in SH3

6. I remember the radio and sonar room in SH3 was a bit larger than the one we have now in type VII boat?

Welcome to suggest any others in this post.
