Ability to add items to the options menu modal

[NicktheGeek]

Is your feature request related to a problem? Please describe.
I am attempting to add a single option for a plugin. The plugin adds a screen reader only text format. The idea is to hide the screen reader text when an element is not in focus so users get a better idea of what the content will look like. However it was requested to make the text visible all the time. I think this is really an option that should be available, so I was trying to add it to the options modal, but cannot.

Describe the solution you'd like
Ideally it would be possible to register options for different sections so that developers could include additional options there.

Describe alternatives you've considered
Since I cannot add an option, I'm adding a plugin sidebar that will use a toggle control and save data to an option field, allowing users to turn the feature on and off. It will work, but not my first choice.

I think in general, it would be a great idea to allow plugins to add their own options to the Options modal. The only issue I see with implementing it right now is that the Options modal probably needs some design alterations to make it scale better with a large number of options.
