[UI] Labelling the interface

[andersonjeccel]

This PR adds documentation for better interface labels.

This looks great, a really good start! I have made a few comments but also I'd request we use quotation marks (" and ") only when indicating actual speech. For all others, use a single quote (' ') instead.

I agree in principle with the recommendations to remove all of the many ways that we use in the UI to indicate the same actions, and instead bring some consistency. This will, of course, have an impact on the translations so we might need to alert the translation teams to this when we merge the PR. It'll be quite a lot of work for them, I think.

I think we should avoid using the word Simple - is there something else we can use instead? Perhaps 'Concise'?

[andersonjeccel]

Simple is different of Concise
The goal here is to convey the opposite of complex

[RCheesley]

Then we should use 'Clear', I think?

[andersonjeccel]

Yeah, it works

[RCheesley]

Could we use anchor links to the headings here? Makes it easier for the user to move around.

[andersonjeccel]

I guess I added everywhere

Still outstanding comments here, plus conflicts to look at. Hopefully quick fixes though!
