I tried to save something on the Notepad menu, but didn't find it back while recalling the window.

Not related to this version: No tutorial file but an entry on it.

What about making a $/resources/interface/tutorials/Tutorial_Notepad.def file with in it:

TUTORIAL_SCRIPT
{
STEP
{
string Text = "Feel free to write and save any information here"

CHOICE
{
string Text = "Close"
}
}

}
