I recently upgraded to 4.0 and immediately hated it because the #1 way I use the application was gone! I depend heavily on my calendar view to see everything I have for each day at a glance. I don't want dedicated time blocks because many of my projects take several days throughout the week, and I have to work on them in spurts but not necessarily dedicated time blocks. But the new feature only allows me to drag each item into a small time block, and it has to be done manually. I desperately need that weekly and monthly calendar overview with the option to drag tasks across multiple days instead of hour blocks. The sidebar view isn't helpful for me at all because I have to scroll, and many of my tasks disappeared. I just want to add a task to my calendar and know that it's a priority for Tuesday and Wednesday, for example. Please, please bring this option back!
