Probably not a major issue for most people but still worth mentioning imo, since I've had discussions about this with other players
It would be nice to have some 'amount' interface when constructing or researching.
Just drag the datacube or whatever into the processor, enter the amount you want to build ( +/- buttons / field for entering amount manually), click start. As long as you have the required raw materials in your inventory, just let construction run until the things are built.
If some people worry about this being too easy.. (Powerleveling research missions Oo ..)
Set a max amount able to be constructed.. like 50 or so..
Not having to tediously drag and drop things from your inventory to the processor for each weaponpart or whatever (knowing that you are going to build 50 or so more..), would be something I know some folks want desperately
