That's a great idea, and though it isn't implemented yet, I have an idea about how to do it (for Yuri). The option to password protect a seperator should appear in the context menu, but should be greyed out unless the expand/collapse option (or maybe the run all option?) is checked. When you choose to password protect a seperator, it should open a dialog box with the standard "Enter your password" and "Confirm your password" text fields. If you chose to un-password protect (or delete, rename, or otherwise modify) a password protected seperator, it should prompt you for the password in a dialog box. If it's a password protected seperator and you click on it (to expand it), the title could change to a text field with the text "Enter password" highlighted inside it, so all you have to do is click, then type your password. The password is hidden by ****'s of course. If it loses focus, it should revert back to the title, if the correct password is entered, it should open, then revert back to the title, if an incorrect password is entered, it should display the highlighted "Enter password" prompt again. Maybe it could even have some sort of built-in question to ask if you forget your password, i.e. if you forget click the "Forgot my password" button from the enter password dialog box that comes up when you unpassword-protect the seperator, then a dialog box pops up with a secret question that was picked/assigned at password creation. Otherwise I think the only way to deal with a forgotten password would be to delete the menu, which is not the optimal solution.
