I used to use Mobile Shell on my 6700 and 6800. Both ran slowly while running the app. I decided to get (close to) the same functionality by installing multiple today plugins with smaller footprints/ resource reqs. DEVSTATE is the best combo between functionality and speed for app management and the Home plugin works well for tabbed interface with all those bells and whistles.
Try Devstate. It's free and VERY useful not to mention customizable. You won't be sorry.
