Add info about Font Overview

[ollimeier]

We have a new page 'Font Overview'. It has a lot of new features and therefore needs documentation.

I have a conflict with the structure of the documentation now, because everything is based on the idea that there is only one editor view.
Please see: reference, there you find for example 'Menu bar', which includes important information based on the editor view. The conflict I have is, that the menu bar is different for the 'Font Overview'. Some parts are the same, but others are different. I currently don't know how to respect that and where/how to store info about the Font Overview.

@justvanrossum What do you think about this:

Also, I am wondering if there is a core feature missing for 'Font Overview' like designspace location via sliders? Before we create the documentation and shortly after that the screenshots/recordings are already outdated?!

The question is, do we have to complete the following list of issues, before extending the documentation, or would it make sense to start earlier: googlefonts/fontra#1886

(While the font overview is settling down somewhat, it is indeed not quite done. I'm not sure when would be a good moment to start documenting. Location sliders may indeed be a good one to wait for, at least for screen shots.)

Regarding the views, "fontinfo" is at the same level as "editor" and "fontoverview". There is also "applicationsettings", which is a little different. More views may follow in the future, although none are planned right now. So, to break it into exactly two parts does not strike me as the right solution.

I agree. It's a bit confusing. fontinfo or applicationsettings are currently sorted under menu bar, but is actually something bigger then just a menu bar item. So, maybe we need to restructure the references page? Oh damn, this is not fun.
