BlogJet looks fantastic so far. It’s another WYSIWYG blog management tool like Windows Live Writer. Blogjet seems more interested in integrating with a wide array of services which is desirable because Onfolio seems to be favoring Windows Live.
ChromaTabs: this will match the color of each browser tab to the dominant color of each site's favicon. For example, if I open a new tab containing figital.com, the tab is colored red because the figital favicon is red.
Tab Effect: this one will "spin your desktop" (Rubik's Cube-style) as you rotate through your tabspace. Slightly klunky but a nice, simple example of how to visualize your task-switching in 3 dimensions.
