Another sweet little hack to throw into your small pieces loosely joined toolkit – this little widget (which you can add to any webpage) allows users to create LaTeX math equations that they can either paste into any LaTeX enabled app or else use the image file that it also helpfully generates. While there are more and more editors that support math equations, the ability to use a widget like this anywhere means this needn’t become a “blocker” requirement that ends up deciding the game in favour of a monolithic system simply because of it’s editor. – SWL
