2.8 - Where is Add Single Vert? + Viewport window?

Where is Add Single Vert?
How to make a render View, Viewport window?

Preferences>>Addons>>Add Mesh>>Extra Objects.


What does question #2 mean?

  1. Two options:

    If needed, set shortcuts.
    For option A to keep as default: File > Defaults > Save Startup File

I’m still learning blender’s workflow. I was wanting to have the 2nd window set as a realtime/render window.
When “render” is selected a separate window pops up and I was trying to avoid that.
Open for suggestions on a good 2 window workflow.

Thanks! …but why not just leave it in Add mesh I wonder?
