Multiple issues with the iOS7 calendar

Bug:

When multiple appointments overlap, They sometimes sit on top of each other, sometimes sit side by side?

Other than that:

The colors are garish - how do I change them?

Can't open the day from the month view by tapping on the day

To skip forward several months you have to go in and out of the year tab - where are my mini month tabs across the bottom

Day view on the right side only shows highlighted event instead of list view

Where is my list view?

Wast of space on the screen when you don't have an event selected

Colors are horribly inconsistent
