1. Like other numerous users have asked, keyboard shortcuts. This is huge for me being a database developer, I like to run keyboard only for most of my work. 

2. Groupy kind of tabs apps together, but all grouped apps remain on the taskbar. When compared to WindowTabs (now open source), the group windows are combined into one icon. Meaning, if notepad, IE and Excel were group together and Excel is the application with focus - only the Excel icon is show on the taskbar (not all 3 applications). If IE has focus, then only the IE icon is show.

Application seems to run well and looks good visually, but needs tweaked for prime time usage.
