The Requests page shows a list of users who have requested access to your Extension(s). Click Accept or Deny to confirm.
In the column on the right, you may see items marked with one of three colors: Filters (blue), Extensions/Sub-Extensions (green), and Individual catalogs (pink) where the Filter category reflects the filters that you have created in the Filters view.
These items here are used for altering user requests and are applied by dragging and dropping an item onto a request in the list. You can use Ctrl+Click to select multiple items, or Shift+Click on the first and the last item in the list to select them all.
If you want to exclude items from a request, use the removal tool on each individual item before accepting the request.
