Calendar should be accessible from Zoho CRM, Why do we have to open a separate tab for Calendar???

Hi,  Our company uses Zoho CRM and Calendar.  I have always wondered why the calendar was not accessible at the top of the CRM with the other buttons. 

Currently in the CRM we see these buttons:
Home  Pulse  Leads Accounts  Contacts Opportunity Email Reports Activities  Campaigns More.....

Even when you select More, there is not link to Calendar.  This is very strange to me.  I would really like to see Calendar added to the list above.
Thanks Steve
