I used to have a pane on the side of the IntelliJ 2019.3 window showing Javadoc for currently selected class name. That pane has disappeared. How do I get it back?
I found this Code reference information page on the IntelliJ site, but it does not help. It shows a "gear" icon in the Quick documentation windoid that might do the trick. My my IntelliJ offers no such "gear" icon.
Select the name of a class in the source editor pane.
Choose View > Quick Documentation.
The pane appears on the bottom right of the IntelliJ window.
Choosing View > Quick Definition (rather than Quick Documentation) shows the documentation in a windoid. To fill the pane on the side, choose View > Quick Documentation as described in step # 2 above.

I'm new to IntelliJ Ultimate edition and I found that others can see the marble diagram of Reactor just like this
... when they hover methods.
But I can only see this (just some texts, without any diagram picture):
Is there any option for enabling to render the diagram?
This is my IntelliJ version.
Open the method documentation by Ctrl clicking the method.
Then choose "Download sources" option at the top of the Editor screen.
Once the sources are downloaded, you should be able to see the diagrams.
Press Ctrl+Shift+A and search and select "Download sources and documentation" as showed in the image.

In VSCode you can hover over a dart class name and it will give you the documentation comments. How do you achieve this in IntelliJ?
I'm using the community edition.
I have tried the cmd + mouse hover but it doesn't give me the comments
it was an option that isn't automatically selected

IntelliJ display Java code auto-completion suggestions in a drop-down menu after pressing CtrlSpace. All other IDEs manage to display the corresponding Javadoc if available. How to get IntelliJ to do that?
How to see JavaDoc in IntelliJ IDEA? refers to displaying it on a mouse hover event whereas I'm missing the Javadoc from code-completion suggestions.
Once you put a dot and the suggestions appear, press F1 (which is the default shortcut for "Quick Documentation" in most keymaps). The documentation for the currently selected method then appears as a card as show in the image. Then you can either use the up/down arrow keys or start typing the method name to select it. The documentation card will reflect accordingly.
You can also click on the pin icon on top right of the documentation card to expand it if required.
I am a new to IntelliJ IDEA and somehow my project structure doesn't appear where It should be. Someone know how to fix this please? I want it to appear left corner where red circle:
You have hidden the tool window buttons. To show them again press Alt+Alt (and keep holding) or click on the bottom left corner icon. Or use View | Tool Buttons to show them permanently. Then you can click on the Project or Structure tool window buttons depending on what you need.
Another way is to use the menu: View | Tool Windows | Project (or Structure).
Or just use the keyboard shortcuts:
Alt+1 — Project
Alt+7 — Structure
You can find more details in the online documentation:
Manipulating the Tool Windows
Currently my IntelliJ shows amongst other things
How do i decide
What tool windows are shown
Where they are shown
Those things are called Tool Windows, and you can find them at View > Tool Windows.
To disable some of them, you can install the plugin ToolWindow Manager and disable one by one.
You can enable/disable all tool windows in Settings > Appearance > Show tool window bars
You can find more information about them here.
These are called "Tool Windows". If you right click on them it shows a menu that at the bottom has a "Hide" option. I notice some of them can't be hidden, but you can drag them to other places that are out of your view. For example, you can drag them from the bottom to the side. You can also drag to answer your second question.
