I've been trying to break away from the last couple of things that have kept me running my Windows 7 VM. Although I use Mail for my email (hosted Exchange), I've always ended up flipping back to Windows Outlook for tasks and calendar management, for the simple reason that it allows me to see my appointments and tasks on a single screen list view (see image). I've tried Outlook for Mac, which doesn't offer the same view. Mavericks has split the Calendar and Reminder functionality, and it's not ideal anyway as I want to see the whole week laid out. This helps with scheduling and those moments when you have to quickly work out for a client whether you can shuffle things around to fit another assignment in. I want (and need) something that handles this like Windows Outlook and I can't believe it's so difficult to achieve. I've also tried Fantastical, but that doesn't do it quite right either - it's more like a list view. I will be eternally grateful to the person who finds the solution!
