Currently there's buttons (when making a new trade or editing a previous one) that let you add a certain effect to your text when selecting a text and press one of the buttons, but earlier today i encountered this website which allows me to set Team Fortress 2 Colors (paint, quality, etc) by just clicking one or two buttons, but selecting a long text on that website is a pain in the ass. i think this kind of features will make the creation of trades easier and more user-friendly.
