First of all, (even I'm certain that they weren't made by lack of knowledge but for the pressure of releasing the product), please don't make the same mistakes present in sh4, for example:

• KM grid, there are remnants of the sh3 grid in sh4, which interferes with the new grid system.
• 3d Objects can't be clicked on the exterior views (uzo, crew) even when they should.
• state machine controller not working as expected (i.e.: in port they should be making random animations as stated in the commands set in the dat files, but instead they're scanning with the binoculars).
• These are a few of the programming problems I found.

Now for new features:

• Better AI (terrain/objects avoid routines, etc.).
• Wolfpacks, not so hard, the basic idea is included in sh4 with the reinforcements/scout routines.
• AI Torpedoes , a must both for wolfpacks and AI ships.
• More than two compartments recognized for the interiors, so we can optimize the work of Tomi and DD.
• Last, but the most important in my point of view is the release of documentation of the format of the files, even when most of it has been deciphered by the community, some parts remain unknown.
