Button to mark read gets pushed off when the username is too long.

Yeah, that’s also an issue for other parts of the app where usernames and magazine names are too long. I’ll definitely add this to my to-do list.

Tangent, I wanted to post using the app but I can’t navigate to the magazine using interstellar. Keep getting 500 internal server error on the fav side bar or unknown error when trying to explore.

That is actually a known bug that was introduced in Mbin v1.8.0. A fix is already present, but it is unreleased. kbin.earth has checked out that code for use so Interstellar won’t cause these errors. I presume you’re using Fedia by the screenshot, so maybe you could ask @jerry@fedia.io if he could also apply the fix (for context, I would strongly recommend using that fix, as the issues caused by the bug are extremely widespread in the app).
