I'm missing two features:
1. it would be great if the blueprint created from the patch planner could be 'undone'
2. I'm using the Construction planner that allows to stamp down blueprints in a 'draft mode' and approve them for construction once you're satisfied with the placing or other details. Your mod somehow places the blueprint down in a different way that the construction planner doesn't interact with.

Maybe both ideas actually would be the same fix, that's why I start suggesting it here :)

Thanks in advance for looking into it

There is an undo button at the top of the GUI next to the title.

About the Construction planner integration, I think this thread is relevant as concept is similar.

Ah, thanks for pointing me to the undo button.
