Thar’Ga can display research costs for all currently available modules.
You can see the amount of required resources that you need to invest in order to research a node.
Problem is very simple. You cannot view and know such information on any other nodes that aren’t unlocked yet or are out of reach.
Weapon, module blueprint, special module, and all the other nodes should have such information present at all times, regardless if you can research previous nodes or not!
This is vital, if you need to plan in advance, especially if you’re limited with resources.
That would be amazing, so you can plan ahead better options considering your resources and desired build. Maybe being able to see and accept the missions to unlock special modules that arent available yet would be good as well.
