I rarely go out of my way to place blueprints in my inventory or the blueprint library. I generally only open the blueprint library when I want to transfer a blueprint between saves. Otherwise, I just place it on my hotbar, go to another planet, and suddenly find the blueprint on my hotbar no longer exists. Because for some reason, placing a blueprint on your hotbar and then clearing the cursor defaults to it going into your inventory rather than the blueprint library. If that behavior was changed, then this mod wouldn't be necessary.
It's literally just 2 inputs.
That's still 2 more inputs than the alternative.
