Switching to use Obsidian mainly through graph view as a mind map. Is it possible and convenient enough as it is?

What I’m trying to do

I’ve been using Obsidian on both Mac OS Monterey and the latest Android version.

wanted to know if it’s possible

  1. to open graph view by design when clicking on a file
  2. to create a file directly on the graph view “canvas” by a shortcut or combination of clicks
  3. link with these files directly through a click operation instead of linking files by writing them within given files between double brackets
    Also, when adding through the double bracket operation, a selection of files shows up but no search engine meaning I have a limited choice as to what I can add which is frustrating.

Wondering if there’s any way to be able to pick from all the files within the main folder

Things I have tried

Having done my research, it seems impossible to achieve so far or at least without any further coding or plugins
