Game Tabs
When you edit a game there are a variety of tabs available to you, some edit various properties of a game, while others let you drill deeper into the game's components.
Design
Designs are the visual representation of a set of components, such as cards, tiles, chits, board, mats, etc. Think of this like an image editor.

Datasets
Datasets are the data representation of a set of components. Each row in a dataset represents all the data for a single card or tile. Think of these like spreadsheets.

Settings
Here you can rename a game, or mark it archived if you're no longer actively working on it. Don't worry, after it's archived you can still access it by filtering to display archived games in the game manager.

Images
A place to upload all the images and icons used by your game.
Variables
Set up global game variables that can be used to set things like colors or sizes, or text, used through-out your game so you can edit it in one place.

Font Palette
Component.Studio comes with thousands of fonts, and you can upload your own. In order to make that more manageable, the Font Palette allows you to select just a handful of fonts that might be useful to your specific game. By default you'll get these 3, but you can add more by hitting the green add more fonts button.
Styles
A centralized location to set set shared font styling and sizing so you can edit it in one place and propagate throughout your game.

Caches
Caches are files generated by Component.Studio on your behalf for things like Tabletop Simulator to use.

Collaborators
If you want someone else to be able to work on your game with you, you can add them as a collaborator. They have to have an account on the site, and then you can search by name, username, or email address.
