Since the new UI update, it is no longer to edit company name/domain name and contact name/job title when previewing their record. I have to do this a lot so it is quite frustrating. I now have to view the whole record to edit and then go back to the record that was I on previously.
I use this function regularly as we have several new contacts created everyday through emails to our support team, and the records often need cleaning up.
The preview and disassociate options are also now a lot less obvious.
