#1 The core ship designs are useless because they are to slow but some of them have nice eye candy. I wonder if Stardock does not let you copy, modify, and save the designs under a new name because the ship designs can't be duplicated in the shipyard. For example, the core colony ship has two colony modules (probably for symmetry) but has the capacity of only one.
#2 This change is no longer needed due to the changes to the UPGRADE button in v1.1.
#5 This change would be a lot less useful do to the rebalancing prior to the 1.0 release. Now new techs usually cost more.
I think #3, #4, and #6 would still be very useful changes.
p.s. Please add an Ideas->UI sub-forum.
