Got it installed on a fresh installation and started testing and configuring, here are my initial thoughts:

1. Settings are straightforward and for the most part self-explanatory. I like how I can specify a separate logo for light mode and dark mode.
2. In the Advanced Features section, it would be handy if there was a link to where you can signup for the GIPHY API key. (A link to documentation would be even better, but a simple link to the developer site would be handy.)
3. For Media Storage, it would be nice if you could specify "Other" and explicitly set the end point for your S3-Compatible media storage. I would prefer to setup a Wasabi bucket, and the same code should work just fine if I could specify an alternative end-point instead of using the existing options in the drop-down. (Looking at the code, you can in fact specify the FLUENT_COMMUNITY_CLOUD_STORAGE_ENDPOINT in wp-config already, it just wasn't specified in the documentation; I have confirmed that it works with Wasabi endpoints just fine. I've submitted a pull request to update the documentation.) It's also strange that you can not specify the FLUENT_COMMUNITY_CLOUD_STORAGE_PUBLIC_URL in either wp-config or in the settings for S3 like you can with R2; I haven't checked what version of the S3 driver you are using but that should be an available option.
4. Courses: I use Presto Player as my video player, and there does not appear to be a method for embedding them or using shortcodes to add the Presto Player. I don't need complicated courses, but don't want to just use YouTube or Vimeo embeds.
5. There doesn't appear to be a way to subscribe to an RSS feed of posts or comments on a specific post. It'd be nice to include that.
6. Does not appear to note if somebody edits their post.

Version installed is: 1.0.70
