The editor offers a choice of 3 drawing tools: Pencil, Filled shape and Eraser. You can customize the tools in the panels on the right by changing their colours, width, and stabilization settings.
You can't draw with these tools, but they can be useful to facilitate the creation of animation: undo, transform, copy and paste, and so on.
All the functions only affect the frame on the current layer.Please note that these functions CANNOT be undone, so proceed carefully.
These tools do not affect the drawing in any way, but they can be quite useful in the drawing process.
Managing frames, layers, and all that.
