My Topics Pack
This gives you all the additional topics in the My Topics view to manage a rich set of different topic and data items. This allows you to convert inbox feed items into additional data types such as projects, etc.
Location + Context Pack
This gives you two new views – Near Me, and My Contexts. Near Me allows you to view items on a map with a built-in type and distance filter. My Contexts allows you to create custom contexts (Work, Home, etc.) to organize items by context by tagging them with one or more contexts.
Extra Inbox Rules
Purchase extra inbox rules in packs of 10, 20, 50, or 100. Once you purchase the Pro.Inbox pack or Pro Inbox app, you will receive 10 custom inbox rules for creating social, email and web feeds. These packs are cumulative. For example, if you purchase the 10 pack and the 20 pack at a later time, you can manage a total of 40 inbox rules (with the out-of-box rules).
Pro Contacts Pack

Extra Contacts Packs
Out of the box, you can manage 100 contacts (with or without the Pro Contacts Pack). You can purchase extra contacts in packs of 100, 200, 500, 1000, or 2000. These packs are cumulative. For example, if you purchase the 100 pack and the 200 pack at a later time, you can manage a total of 400 contacts (including the 100 out-of-box contacts).
