I'll just mention, in case it's not apparent, Interstellar (the app) does support swipe gestures on posts and comments; you just need to enable them in the settings. I do realize the Blahaj PieFed instance hasn't even enabled the API, so the app wouldn't work with piefed.blahaj.zone yet.
Unfortunately, it's not that easy on the fediverse. My instance, kbin.earth, still has the original image, and I'm guessing mine's not the only one. Once something's published to the fediverse, there's no going back :)
@TyrianMollusk@infosec.pub Yes, that is correct. There's no way to register for an account through the app ATM. You'll just have to do so through the website.
Writing this message on the interstellar app just now. My only minor gripe is that there's no way to mark something as read with a single tap that I've found. (Got to long press and mark as read, but I'll accept that I may have missed something)
I'll give a quick overview: to mark a post as read, you need to either open it, vote on it, boost it, or mark it as read explicitly, which can be done through the overflow menu (long press or tap overflow button, like you said) or by configuring the swipe gestures to have the mark as read action (then all you have to do is swipe on the post). In the next update, we will also have a "mark as read on scroll" option, which, when enabled, will mark all posts in your feed as read once it scrolls off the top of the screen.
Interstellar is also available for desktop platforms (including Linux and Windows) if you'd prefer to try it there instead (check the GitHub page for info).
I'm sure you know, but technically, Microblogs are still considered "posting to your profile". It's just that Mbin also happens to categorize those microblogs into a specific magazine, either based on tags or manual placement. They still display in your profile just like normal. Additionally, if you view those Mbin microblogs from a Mastodon server, they will still appear as if the user "posted to their profile". All Mbin is doing is assigning the Microblog a general categorization.
I changed kbin.earth from kbin to Mbin, and it's been working great. It definitely helps that Mbin is a fork of kbin.
