This add-on has been saving me a lot of time. Before I knew it, I converted the LaTeX codes manually, making me hate it more every time. Now, it only irks me, but I can cope with it when (absolutely) necessary. I found a bug: strings like 2^22^2 aren't converting, the add-on chokes and spits the strings unchanged. It should convert to 2222. If a space is added, like 2^2 2^2, it converts correctly, though. Maybe it's a TeXZilla bug, as the add-on is based or uses it.
