The OmniGroup is previewing OmniWeb 5, which is to be officially announced during MacWorld Expo. To the left you see what they call ‘Workspaces.’ Basically you can book mark a bunch of sites and store them as a Workspace, quit OmniWeb and then restart and they are still sitting in your workspace. You can also send a file to your OmniWeb 5 using friend that they can open and see your workspace. It is very cool, and I think one of the best new features of the product (which I haven’t used yet, so this is all based on the product description).
