As the title reads. Given this mod is specifically for interacting with blueprints, might it make sense to have it available (attached) to the side of the blueprint window? Or perhaps only show a button when there is actually a blueprint "in-hand" ?

Just seems a little silly to have it always available when it's typically, at least for me, not used often.

Thanks for the suggestion. I will look into it. But as i am not the original author i am not yet familiar with the options.

Raiguard has some mods with clever context sensitive GUIs. One that could be some good inspiration for this could be Quickbar Templates. I believe the little GUI button only shows next to the quick bar when you're holding a blueprint in hand. Pretty neat.
