The Front Salesforce plugin is great for logging emails to SFDC on an ad-hoc basis!
However, if you have multiple SFDC contacts on an email, you have to log the email to each of their SFDC profiles individually. It would be an amazing time-saver if there were a multi-select dropdown to pick which all cc'd profiles you'd like to log the email to AND if there were also a "log to all button."
We frequently need to log emails to multiple profiles at the same time, and other plugins we've used in the past have had this very helpful feature.
