After upgrading to 2018.3, the Undo button disappeared from Toolbar. How can I add them to the toolbar? I do know how to get Customize toolbar window...but I find no way of adding the Undo button to the toolbar.
Yes, you can add Undo/Redo actions to the Toolbar like this:
Note that Toolbar needs to be enabled in the View menu:

By default, in IntelliJ, the main toolbar is hidden. When it is hidden, there are essential buttons that are shown in the navigation bar. I don't need the full toolbar, but it would be nice to be able to add a single button to the navigation bar.
How do you add a button to the navigation bar?
You can customize any menu or toolbar in IDEA in settings by going to:
Settings-> Appearance and Behavior -> Menus and Toolbars
The item you are looking for is called
Navigation Bar Toolbar
There's the navigation bar and it's possible to hide it in menu. But, in the last version IntelliJ IDEA added another kinda navigation bar.
It looks like an editor gutter but placed at the top of the active editor. It show the name of the class and method with the current caret position.
Is there a way to hide it?
To disable this feature, uncheck Show breadcrumbs in Settings/Editor/General/Appearance.

I have seen that the back/forward buttons in IntelliJ-IDEA 13 have disappeared.
Any way to bring them back?
You have to enable View->Toolbar to roll everything back! ;)
I prefer not to add the whole toolbar, but add the back and forward buttons on the Navigation Bar Toolbar, which is probably already visible:
You can do this by going to Settings->Appearance&Behavior->Menus and Toolbars and there you can add the back and forward buttons to the Navigation Bar Toolbar. They are under Main Menu->Navigate menu.
I think this is much better than losing a row for the toolbar. To contrast this with the above image:
I'm trying to implement my app's settings. So I implement Preference Pane but I need to insert Toolbar to it. That is how looks my IB:
And this is how looks my pane from System Preferences:
You see, my window new height = old height - toolbar height. This is my first time I work with toolbar and prefpane, can you answer is there any restriction to use toolbar iside of prefpane?
The System Preferences application already sets a window toolbar so you cannot have a toolbar in your preferences pane.
I recommend using tabs; look at the NSTabView and NSTabViewItem classes.
Note that NSTabView does not actually require tabs to be displayed (though I recommend making tabs visible to the user). You can configure NSTabView to have no tab frame and still take advantage of it for panel-swapping.
