This is a great mod. It adds something I believe Factorio needed from the start. Although, I often find myself hitting "E" or "Esc" keys to exit the "Player stats" GUI. After digging through your code, I did realise that "I" can be used for this. Although, "I" is a little far from the other usual keys. I'm not sure if this would be too much of a hassle or would even be possible but would you be able to add keybindings for "E" or "Esc" or even both - atleast to close the window - as the primary inventory panel of Factorio permits. In the case of this not being possible or too difficult, would you add a key in the GUI open box such "I to open" or something like that of your choice as a means of assisting future users of the mod. Aside from that, your mod is awesome and is basically polished to perfection. Thanks for your mod and any help in advance.
