Preference settings UI and enable/disable to be more easily understandable

This is my first time using devdocs and I'd love to continue using it because it's bound to be useful for me.

Therefore I took the time to explore the functionalities a bit and enabled some docs. All great, until I wanted to disable some of them. Personally I had a bit of difficulty trying to understand where exactly can I disable, until I figured out that you can do so from the preference settings.

My confusion stems from:
1. If there is an easy quick way to enable docs without going to the preference settings, why not create a symmetric functionality for the disabling of docs
2. The way the preference setting is laid out is in such a way that I think first time users would think that the settings are supposed to be applied individually to each docs due to the checkboxes (which now I know is actually for enabling/disabling)

If this is not a concern I can understand, but thought it would be helpful for a better UI/UX
