I would like to 2nd/3rd/nth the requests for better Non-IE web support. I work for a non profit with hundreds of users spread across the globe so have little to no control over their system choices since I never see most of them and they purchase computers locally.
I applaud the efforts to make more management tasks doable via the GUI instead of just in powershell. Exchange 2007 RTM was severely lacking in that respect with even common tasks like Send On Behalf permissions requiring long power shell commands. In small/medium organization's IT depts. we need to be Jack of All Trades (and masters of none) since 2 or 3 man IT depts. don't have the manpower to specialize in Exchange Management and memorize the long powershell commands.
And single mailbox/item restores when using DPM server is also a concern of mine. The current official method is long and clumsy.
