Paste block of code including newlines

[Splines]

Thanks for your awesome plugin, this is so helpful!

I was wondering if you could possibly replace the one-line LaTeX code box with a text field that also accepts newlines? This would improve my workflow a lot as I'm copying LaTeX code from an already existing LaTeX document. When using environments like equation and align, usually commands are split by newlines to make working with long equations more relaxed for the eye. For right now, I have to replace all newlines in that document with empty strings, to be able to use your plugin.
