it really has no bearing on how I manage my account and just takes up screen real estate. Also, I want to be able to search all of my campaigns (or "emails" as I guess they're now called), not just one tab at a time.
The calendar on your home screen would not be removable. This is just a hardcoded feature that will display regardless if emails are scheduled in advance. I'm happy to pass along a feature request to have this configurable from the home screen, however.
The search bar found when click on the 'campaigns' portion at the top of your account would only search that particular tab. You can click between the status tabs and it will apply the search string when you switch to the desired tab. This ultimately results in faster search results overall.
