Hey! The LaTeX feature is still brand new and I'm looking on improving it, thanks for the feedback. The PDF export seems to be misinterpreting the code blocks, I'll have a fix out tonight! (Edit: done!)
I would describe it as more than a math-enabled notepad with support for 6 other scientific block types and the ability to run code. However, I agree that it's definitely not built to write full blown scientific papers at this stage :)
