Your company's set dressing
This is a place to keep track of the set dressing your company owns or can use in its projects. You can define your set dressing in terms of categories and sub-categories, and then add your own tags -- any short words or phrases you choose -- to make the description more compete. You can also add pictures, manufacturer information, asset IDs, and other details about the items.
Once you've done this, you can assign your set dressing to your projects, scene by scene. This will add the items to any call sheets for those scenes, and should generally help you keep track of where you're planning to use your stuff.
The idea here is to list all the items you have access to, for use in all your projects. When you're setting up a project, you'll be able to choose which of those items will be needed for that project, and even in which scenes they'll be used.
