Show a single Category highlighted (on top) on Region-page

[elwinschmitz]

(from user test in Nijmegen): To have a category 'where to go first'.
I can of course make this category myself, but I wanted to talk with you also about the possibility to make this design bigger, so to give it the format of for example three categories, to make it really visible for people. Because in the end you want to make it very clear for people where they can go first for help.

Possible solution: Extra Category-property

We could add a "pin"/"sticky"/"highlight"-property to a Category.
So in the sheet we'd have an extra column with a "Yes/No"-field per Category.
This would switch the layout for that category to "full width" or "regular single block".
(Like in #112 )

Downsides:

• needs another column in the sheet
• needs changes to (all) sheets
• only for 1 small layout-change

Possible solution: Using Markdown/HTML links

We could use a Markdown or HTML-link in the sheets' Introduction-text. This will be shown above the list/grid of Categories.
For example: https://green-pebble-0707a6b03.azurestaticapps.net/example

...introduction text...

<a href="/<region>/start/" class="action"><strong>→ Start</strong></a>

Downsides:

• currently ALL Markdown/HTML-links (even local/relative ones) will open in a new window/tab
  Possibly work around that with plugin: https://www.npmjs.com/package/markdown-it-link-attributes See Let relative/internal links in HTML/Markdown-content NOT open new window/tab #649
