Locate the Drawers

There are two areas which represent the two Drawers, one located at the left side of the TVPaint Animation window, and the other at the right side. The two Drawers are enabled by default.

The 4 main parts of the interface

On this screenshot, you can see that the workspace can now be divided into 4 main parts :
1) The Project window
2) The Timeline window
3) The left Panel Bin
4) The right Panel Bin

Almost all the panels in TVPaint Animation will be able to be stored in one of the two Drawerss.
