Switched to the TestFlight version of Arctic, and was pleased to see the block list filter for Lemmy Explorer in effect, working great! Still have to dig through the settings and use the app a bit more to see any other differences that are in the TestFlight version versus the App Store version, but two things quickly came to mind. Decided to split it into two posts to avoid having an exceedingly long title.
Upon checking my user page in the updated version, I noticed stars next to posts I had made in communities that I’m subscribed to. Although I’m glad the option to mark such posts is there for users wanting to distinguish them, an option to disable the stars and make all posts appear in a uniform manner would allow the end user to choose their preferred display style.
Edit: The feature requested above was already implemented, per the comment below.
There have not been many major changes in this the TestFlight build for this cycle. Mostly small feature additions and bug fixes. The best way to look at the new features it by viewing the Changelog (Settings -> About -> Arctic Changelog).
There is an option to hide the subscription indicator next to community names, albeit it is somewhat buried. (Settings -> Appearance -> Community Label -> Show Subscribed Indicator). There is also an option there to show a Favorite indicator, but I believe that is disabled by default.
