This feature shows the emotes when you click on them, when you click the image icon you have to input the url into a box and it shows the whole image. Same with fonts, spoilers, text effects, it shows some urls in blue when quoting, it adds an extra space between paragraphs, and can add unnecessary formatting throughout the whole post. This is really annoying for me especially on mobile, when the buttons don't want to work at all and I'm stuck with manually inputting all forums code on a touch screen.
