You can organize the list of apps on your My Apps page by creating and assigning categories for all the apps that appear there. Doing so lets you group similar applications together for sorting and search purposes.
Tip: You can create and assign a category in one step, if you want. Read how.
To assign a category to an app:
On My Apps, switch to the details view:
On the app's row, click the drop-down in the Category column and select the category that you want to assign to the app.
Your new category assignment for that app appears in the list.
