When you send emails directly from the CRM you can view a preview of it. However, if you save documents/emails in the CRM there is no ability to see a preview. It would be great to have this feature so one could preview the document/email efficiently on the activity notepad.
You do now get a preview in the activity, but maybe a "show more" or open a full reading popup/popout panel would be nicer than having to click into the document full detail window when you want to read more than the limited preview.
