I've been a faithful ACDSee Ultimate (and now 365) customer for quite a few years and while the product always answered most of my needs I now find it lacking quite a few features, among them (modern?) file format support. Other image viewers that I won't name do support these and I'm really considering switching...
Here are a few formats that I wish to see supported in the next ACDSee release: SVG, AI, EPS, WEBM, animated PNG

Thanks for reading and considering my request!
