Export block

Hello ,

I need the ability that
1. Only the admin user can export/print the leads and contacts . No other user should be able to do that . If there is some option is that feature available for all the versions or only for some specific versions
2. Accept for the Admin user no one should be able to delete the leads, again if there is some option please specify the versions.
3. Is there an option to select fonts for emails while sending the emails through zoho crm?

Regards,
Ankit
