Chrome OS looms ever closer, but still there are a number of enhancements and changes being rolled in that should make for a somewhat nicer experience, and TechCrunch has highlighted a few. Perhaps most major among those changes is the ability to browse the internet without signing in, but if you want to update your bookmarks or save any form data you'll still need a Google account. There's a new side bar that appears to give access to other apps, replacing tabs on top, and it also adds in battery and WiFi strength indicators. There's also something of a debate going on regarding whether Chrome OS should have support for compressed archives (.zip and .rar files and the like). Right now the OS has no support for those files, which, as one contributor points out, is rather unfortunate given that Gmail itself generates zip files when you click "download all attachments." Let's hope someone at the Googs finds time to add that in so that future users aren't locked out of the joys of extraction.
