Quite often I accidentally close an IE window by mistake. It would be very handy to be able to reopen the last closed window using an File-Re-open Last Window option. Not sure if this can happen, but when I accidentally close an IE window by mistake, I would like to be able to do a Control+Z to undo it and have the window open again. I would like to reboot my PC and all my IE windows come back. Note: Firefox allows you reopen your tabs.
