This page shows the Shelvesets for the selected repository. By default, Shelvesets for the current user will be listed. To see other user shelvesets, select a username from the dropdown in the Shelvesets header bar. You will only see shelvesets for repository folders that you have access to.
This table has columns for the Shelveset name, the date, creator, repository path, delete and comment. Clicking on the Shelveset name will take you to a list of items in the Shelveset and will display the Shelveset comment. Click on an item in the Details column to diff the Shelveset version against the repository version.
