In Tact you can see a list of your logged activities to Salesforce in the detail screen for a Contact, Company and Opportunity. Each detail screen is divided in to sections such as Recent Activity, Tasks, Related Contacts and any other information that is relevant to the Contact, Company or Opportunity.
When any activity or task is logged to Salesforce there will be a cloud icon to the left of it signifying that it has been logged to Salesforce. Here is an example of what logged activities to Salesforce look like in each detail screen.
