Ok, I thought user is all about permission and if I create a user and set all permissions to check, then it's like admin level user. But now I think I'm wrong.
so I created a user_lead and assigned author unto it to measure it's capabilities.

then I checked all permission

Yet still I'm unable to see the template here (never-mind my port 8080, I configured it that way)

but if add group administrator with same all checked permission, I'm able to see the template, but my question is WHY? please somebody explain
