Toolbar, Onion Skin and other basics in OpenToonz

Toolbar, Toolbar options, Consol and Onion Skin are hidden in the Cleanup room of OpenToonz by the default. Where can I find them to start drawing or animating some objects?

Right-click on the scene, go to Gui Show/Hide, click on Toolbar, Tool Option bar, Consol to activate them.

Now this bars are opened and you can start to use them.

To find where you can turn the Onion Skin option on, go to Customize-Preferences-Onion Skin. Here you can also change the colors of Previous and Following Frames Correction.

Then make sure Onion Skin is activated.

Done!
