You should be familiar with the names of the window elements:

Workspace Screenshot

The most important elements are the sprite editor, the timeline, and the color bar.

The timeline is not visible by default, you can make it visible from View > Timeline menu option or pressing Tab key. (Also it popups automatically when you add a new frame or a new layer.)

You can drag-and-drop tabs to a side or duplicate them using Ctrl or Alt keys:


Color Bar | Context Bar | Sprite Editor | Status Bar | Tabs | Timeline | Tool Bar
