New version?

I like the "new version" template for Zoho CRM but one change I don't like is the fact that the Calander module dissapears from the side bar. I know it has been added as a button on the top menu, but you have to click on it to display it. Can the module be added back to the new version? Also where can I set the paramaters for the time that is displayed? It currently display 24 hours from 12am and I only need form 8,00 am to 8pm. Also can I still set categories for items like in Outlook?
