Zoho Mail and Zoho CRM

Zoho Mail and Zoho CRM

Using ZOHO mobile version there is no way to see the email associated to a contact or to a lead, this makes ZOHO useless on the move, and this is opposite to the trend in the CRM industry. 
But also moving from IMAP to POP configuration, as I had to do recently to integrate ZOHO and ZOHO mail , you will lose all the associations between Deals and Emails....
I had 1 year of work spend associating each email sento or received to the related deals and all this job is gone. And I cannot even fix it now manually since it is no longer allowed.

This is senseless. Also in the ZOHO mail i do not have any contacts taken from the CRM, So I have to create it by myself...
It would be nice if ZOHO MAIL and ZOHO CRM would have a real integration, as other CRMs have, for example allowing the user to associate a certain incoming (and sent) email to a dea, a project or something else.
This was available using IMAP.. but it is lost when I had to move to pop settings..
