People Hub : Twitter Support. Allow me to chose what FB info to see. Ability to save photos posted by friends. Indication of and the ability to read responses to my updates or posts I responded to. Quicker updating of the hub - sometimes it takes 30 seconds just to download a few updates. The 'Recent' screen is kinda useless..maybe use that to display the responses I mentioned previously.
Photo Hub: Ability to save photos posted by friends. Post to Twitter integration.
Email: Conversation view. Black background with white lettering. Choice of auto-downloading pictures. Better integration with Gmail as far as starring, deletion. Viewing emails in Sent folder. Flagged and Urgent messages *remain* in respective views until un-flagged or marked not urgent. Outlook accounts get the ability to sync by push during certain times and scheduled sync at other times just like in WinMo 6.1
Me Hub: Twitter integration.Me hub should be integrated into People hub in my opinion.
MarketPlace: Fix the scrolling/lag issues and the crashes. New apps should be listed first in every section.
Calendar: The hub tile is too austere, needs an image of sorts. Month view needs to have the appointment descriptions more visible or use color coded bars based on 'personal', 'work' and other user created definitions so we can quickly and easily determine what days are booked in month view. In month view, clicking on the day should bring up a list of the appointments for that day only, not the view of all past and current appointments..or even a list of the appointments displayed under the calendar.
Music/video hub: The hub itself should be the double hub on the start screen with the ability to display a transition of user selected album art or Zune band art. Higher resolution background images. Icons of past and paused videos should be smaller in History view.
Maps: Faster performance. Street view, integrate the compass, bus schedules, contacts address integration, save favorite places.
Notifications should remain persistent until they are addressed.
Apps need to save state in a better manner. I am tired of seeing that 'Resuming' notice.
Custom tones for ringer, text, email and all notifications.
Individual volume adjustments for ringer and music.
Auto correction for every instance where the keyboard is used.
