That looks great
Having seen the Home-Page without the Bottom-List my first impression is I would like some kind of small Buttonbar at the bottom of the page instead, rather adding custom-buttons for shortcuts there instead of adding them to the menu. I would at first think of having direct buttons for going to library, shortlist, browser and search...
Then, like for the browser in the menu or in a buttonbar, we would need icons...
If you tell me what the ideal format and proportion would be for additional icons, I could create some, maybe as a start for the browser in the menu as seen above and new one for the tweaks... For airplane-mode there is probably already one in the system that could be used
