If you haven't been following the Interstellar magazine, I've added a lot of functionality since the last thread here, including views for magazines/users/domains, better navigation for wider screens, QoL additions (like the @ button to reveal originating domain, inspired by Artemis), and a lot of different bug/functionality fixes.
This latest update finally includes the ability to log in to a kbin account, and it's not even restricted to just one; you can log in to as many accounts (or view them anonymously) as you want.
Now that you can log in, you can also vote/boost threads and comments. In addition, you can subscribe/follow any magazine/user/domain. Finally, the feed view has tabs for Sub/Mod/Fav/All when logged in.
For would-be testers, here's the link to the latest working build: github.com/jwr1/interstellar/releases (AppImage and APK).
The new kbin.earth server (open registration and API enabled) can be used for people wanting to test the app logged in, or maybe you just want to try a different instance.
Feel free to post any bugs or suggestions in the comments, on GitHub, or on the Interstellar magazine.
Edit: Here's a link to the matrix chat room: kbin-interstellar:matrix.org
BTW I highly suggest you make a launch announcement on places like m/KbinMeta here with github downloads linked to get more users' attention
EDIT: I think you made a concept post here a while ago?
Honestly, that's pretty much what this post and the previous post were for. I'll probably make future posts for other major milestones here as well, and smaller milestone posts are on the Interstellar magazine.
