Since Extended will soon allow TRP users to see creation links in chat, it isn't a far-fetched idea to allow TRP users to inspect Extended users' inventory as well.
The reason to suggest this feature is to make the inventory more attractive. People will usually use their description, Currently or At first glance to fully describe their character gear, even when using Extended, since regular users wouldn't be able to see the inventory.
Coupled with #37, this could help the attractiveness of the inventory by a lot. Editing your inventory would still require Extended, since the creation database is tied to it. The "Inventory" tab could be shown for regular users on the main TRP window, with a warning to install Extended to access it.
