Alfred Astort over at the Windows Phone Development Blog has a great list of things to check on when finalizing development of Windows Phone 7 apps. The list looks like a great resource for any developer looking to improve his app before launch. Among the items are tips on start tiles and splash screens, keyboard improvements, and most recently theme management. Hit the link for the full list and check back on the Windows Phone Developer Blog over the next few days for in-depth explanations for the rest of the items on his list.
