HTML Variants and Campaign Sidebar to be removed

We recently shipped the ability for admins to put raw HTML in billboards — enabling more content flexibility while still leveraging targeting and optimization.

This new functionality allows us to remove some other features which are no longer as relevant given these upgrades:

• HTML Variant
• Campaign Sidebar

We will start by simply removing the references to these features from the admin navigation (while technically still configurable if you navigate directly), but will entirely remove these features within the next few months.

While billboards should be able to technically replace these features, there are still some additional features we will add to really make these as useful and friendly as possible.

We still encourage admins not to over-use fully custom HTML as it could create bugs. It's safer to rely on markdown.
