better menu/ interface for in game construction

[andrew2scott2]

This may have been said be for.Im sorry if I am.

I found this game. I love it to tell the truth. But I find the in game menus / interface kind of overloaded.
I'm talking about the menu you get we you selet to build something. Like a defense turrent or hard point.

Would it be possablie to add a filter to the menu or simple cut the lesser versions of a turrent or hard point out of the menus once a better version is researched.

I also suggest the same for weapons part of the building of tanks.
