[META] Edit perspectives user experience

The solution for no-javascript could / should be to not display the tabs at all.

The wrong non-js behavior and proposed change makes these related..

Removing itself from the related task list.
This is a meta, so the typical design is to make the individual tasks children.

Am I the only one who thinks the current UX of paragraphs behaviors is less than ideal? A typical editor scenario is this:

1. Editor adds a new paragraph at the very bottom
2. Now the user has to scroll all the way up to switch to 'behavior' view
3. Now all the way down again to configure the newly created paragraph's behavior
4. Now all the way up again to toggle content editing
5. Now all the way down again to add the next paragraph
6. WTF?

@smk-ka That's the price you pay with step by step implementation. We divide into small steps that are acceptable because we know we can easily remove the pain points.

The solution to this problem is here, long proposed. But no one considered contributing to getting it done.

@smk-ka we are always open for new features and proposals. :) We also need more patches to get the things done. :)
