Does it have banner blocking (not just the wide and thin ones... there's other ones that are more square that OmniWeb blocks). Can it emulate other browsers so that it can get around stupid browser blocking? Can it automatically check for updates and download new ones (INCLUDING latest beta builds -- or in OmniGroup's case, sneaky peek builds)? Does it have a built in source editor/links viewer? Can it keep JavaScript and applets disabled until you specifically click to invoke them? Does it antialias the text on the website? Can it block ads that have a certain string in the URL to them, or better yet, can it block ads that are not from the site that loads them?
