People's creativity always astounds me when it comes to how the Start Screen's arranged. (as proof of that, I haven't had time to rearrange my screen yet ;___
I do have a question, though. I've been debating to try what DCTF and others have been doing (minimalist start screens), but part of it is inertia and part of it is what "workflow" I have on my phone works. I'm assuming you guys find it easy enough to use your phones in that fashion, or don't mind going to the app list to open apps that might not be on the screen?
There are different ways to handle it. You can make the main chunk of the screen with this minimal look, maybe giving preference to the tiles that give you notifications that you need to see most, and then leave a pool of icons filling the screen below (so you only see them if you scroll).
You could make lots of use of combined folder tiles, but obviously that's only good for tiles which can remain static, and for which you need no notifications.
Otherwise, it's just a case of being very strict about how much you really need a Start tile. I realised, for example, that I don't really need People (the app, not... you know what I meant). It's accessible within Phone, so the extra tile is redundant. I'm very much hoping that Outlook will behave as a single app tile in the final WP10 - they're the same app, so it would be nice to have a single tile that flips between email alerts and calendar info. Do we really need maps on the Start screen? Probably not, but there will be days when we do. That's partly why I added that scatter of small tiles. It's partly because I like the look of it and the way it makes the illusion of depth, but it's also so I can throw a tile on that I need for that day. If I'm going to be in London, I can throw on the Tube Map app for that day, or if I'm going to an unfamiliar city I can add Here street maps or the City Lens.
