I just installed this mod (v1.1.1) into Factorio v1.0.0. I've never used this mod before so maybe I'm missing something, but the mod appears to do nothing. I selected the tool (Control + w) and drew a rectangle around a big-pole and nothing happened. Nothing happens no matter how I draw with the tool. Is this mod broken with v1.0.0 or am I doing something wrong? Thanks!

Hi there. This mod hasn't been updated in a while, so it probably needs to be changed to work with the new version of Factorio. I will try to find some time to do this over the next week or two. Check back here for updates.
Thanks for your interest!

Updated finally, but for 1.1.x
