I was using this mod last night, and was trying to get things out of a chest that was under radar cover far away. I found I had to have an item in hand and then left click on the chest to open the chest. If I had nothing in my hand the chest would not open. (Factorio base bug or a mod bug?)

As of 0.16 this has stopped working - it was a bug that permitted this in the first place and has been removed:

"Fixed it was possible to open entity GUIs from zoom-to-world when holding some items in cursor."
