SVGs are just so powerful. Last week there was a problem with a parallax transparent image with a filter: drop-shadow looking awful on mac safari and ios. Solution was to create an outline of the image in an SVG and use an svg filter with feGaussianBlur for a drop shadow. I feel like I'm only scratching the surface on what's possible with them. I've been using svgomg for my optimizations, but this looks to have quite a bit more useful features.
