The original layout was better being able to select a time for a resource based on a list of available resources and when it was booked; this allowed an at-a-glance view of everything, especially my own bookings for the day. Then simply pressing the sideways arrow to navigate to the next day etc was extremely handy. Having all that gone and now having the screen pop up to be half the size to input data is terrible.

Also, when I change the date of the booking, the "end date" doesn't change automatically, causing an error when I try to submit, losing all changes and forcing a start over.

EDIT: I now realise there is a calendar view but it is not default and the graphics are way overblown/large, limiting the ability to see everything at a glance.
