You "dont use rar"? Why not just download winrar (it is free), and use it to extract EVERYTHING, including zip and 7z? Why do people complicate things by using different apps?

By the way, i agree that the stars gravity well needs to be as big in relation to their mesh size as the planets gravity wells are. In essence, mucho grande!
Also, i approve of halving every supply cost for ALL the ships

(will still keep the supply balance)
And a question, did you leave the damage and hull/shield points of all the ships and abilities at normal (latest patch)?
I'd not really like if this mod changed any basic balance things like that. I'm okay with making capital ships stronger like doubling or tripling the hitpoints and damage. And also with increasing fleet support and squad caps.
But i'd hate to see this mod that has so many superb changes, go overboard and change EVERYTHING

I think simplicity is the key here. Like your tripled Base Defence damage values. Very good! As long as the ships and abilities stay like they were intended, balance-wise.
As long as you just change the things annoying us at the moment, like the uselessness of the defences and the puny capital ships, its going to be an awesome mod.
Truly Enhancing the game, instead of wildly changing it in terms of every single hitpoint value of every ship
