There are multiple ways to view and find packages in your catalog.
Go to Package Explorer by clicking Start > Catalog > Manage Packages.
You can view up to 250 packages per page via the dropdown menu in the bottom right corner of the interface. Pagination controls are displayed along the bottom.
Your packages are displayed in a grid. You can change what fields are displayed in the grid via the Layouts section of the ribbon.
Search Field
The Search field is one way to filter your packages.
Column Filter
Most columns in the grid have a filter button to narrow your results.
Column filters only work on a per-page basis; for example, if you have three pages of data and apply a column filter, that filter only applies to the current page. If you are looking for filters that will affect all data regardless of what page you are on, use the Search Field, Quick Filter, or Queries.
You can use the buttons in the Type section of the ribbon to easily filter one particular type of "Package."
Quick Filter
There is also a Quick Filter function to filter your packages even further.
Layouts
You can change what fields are displayed in the grid via the Layouts tab. There are some preset layouts in a dropdown.
Each layout has specific columns. Although you can resize and move columns, your changes will not be saved for the next use.
