Deactivate Node Tabs

How can I deactivate the standard Node Tabs in the 2.8 Node Editor?

Like in 2.79, press T key.

Hi zeauro,

many thanks for your answer.
But I did not want to hide the Tool Shelf but I want to disable (hide) the Tabs.

You have to edit python UI Scripts if you want to remove something exposed in a region of an editor.

In 2.79, you can do a right click on a button in such toolbar and choose Edit Source item to modify the corresponding script in Text Editor.
But in 2.8, python API have to be completed to handle 2.8 changes.

If you try to edit Tool Shelf for shader editor in space_node.py script, you will find nothing.
Node editor has been split into 3 new editors. So, this part of UI is handled internally, for the moment.
New scripts have to be written to reflect this change.

Thats what I feared.

I appreciate your help.
