This widget is represented by an orange bar graph and the title To Sync / Remotes.

At a glance, this widget will tell you the total number of records that need to sync across all remotes and the number of remote databases for the database you have selected.  
 
This widget is more valuable when you have a database with remotes. This is to ensure the sync health of the database because, if the number of records that needs to be synced becomes to high, it may cause time out issues and other problems with the Act! Database. 
 
When you click this widget, you will be directed to the Remote Database page.  Managing Remote Databases is covered in more detail later in this documentation.
