I´d like to take the last chance in 2016 to second these suggestions:

Btw: have a great new years eve, all of you!
Want to request again two features that would be this great.
1. Logo added to email
2. Ability to put an announcement at the top of the email
All small suggestion!
Is it possible to get a text area where an admin could post a few sentences, that are displayed above or below the digest?
Andy, any chance to have this included? I know you haven´t built this digest to feature a newsletter thing with manual input. But I guess in the meantime it´s obvious, that many here would love to have an optional and shortend opportunity for at least a text-field and a logo. Come on, dude..please@AndyB, a feature suggesstion if you're looking to add ...
I'd like to be able to get stats on page loads originating from the Weekly Digest email, using Google Analytics. It only takes the addition of a URL parameter at the end of the topic link URL. For example,
https://site.com/threads/title.231445/
... to become ...
https://site.com/threads/title.231445/?utm_source=WeeklyDigest
The utm_source value could be added as a field within ACP, and if it contains a value then it's appended to the thread (and unsubscribe) URL's.
