Hide it add-on:

Hide your selected object or objects with a button.
They will be hidden in the viewport and listed in your 'hide it' panel.

Just select your objects and press the 'hide selected' button.
Of course, the H key can also be used to hide the object.

The objects will appear in the 'currently hidden objects' list.
Next to each object, there will be a 'button' to unhide the selected object again.
Or, in the outliner, the eye icon can also be used

The 'hide in render' checkbox on top, can be used if you also want the objects, not being shown in the render.
But keep in mind, objects set hidden with the H-key, will not be hidden in the render

The 'unhide all button' will unhide all the hidden objects in the scene, even those that were hidden by using the outliner

If the 'unhide in render' checkbox is checked and you unhide the object, the object will be shown again in the viewport and in the render.
This is also the case if the 'unhide all' button is used.


There is also a 'unhide last' button.
If pressed, it will unhide the last object that was hidden.


Objects hidden by using the panel or using the outliner
It makes no difference. The 'unhide last' will show the object again in the opposite order of hiding.

And with the 'unhide steps' selector you can choose how many 'unhide last' steps you want to go back at once.
And the steps, they can be changed whenever you want.

Hiding vertices, edges and faces is also possible.
You select your mesh, and in the dropdown in the panel, you select vertices, edges or faces.
Your object goes into edit mode and you select the part of your mesh you want to hide.

Press the 'hide selected' button and your selection is now hidden
The H-key can also be used, to hide the selected part.

You can select one or more vertices, edges or faces at once or in steps.

The unhide last button, will unhide the hidden parts of your mesh, in the step that was set in the selector.
You can undo the steps until the mesh is complete again.

And of course the unhide all button, unhides all at once.
