Plugin or Client that allows multiple GUI's to function at once.

Ive been trying to find something that will allow me to use a keybind/macro while the crafting table window is open. For instance, I want to be able to type while I have the crafting table window open or press a binded key to warp while crafting is up.

Is there any client or plugin that allows for this? I've been told you can edit the Java code to allow multiple gui's to function but I am entirely Java ignorant... Any help is Muuuuuuuch appreciated!
