The design isn’t up to date. But, I sorta liked the idea of keeping it compact but each post and comment thread can open into separate windows if you want to keep something alive while doing something else. What do you think about this approach vs. a normal sized window/resizable window with a custom MacOS experience.

Edit: To be honest, I’ll definitely make it resizeable and mybe the tab bar moves to the left side so the main window feels more “Mac App Like”
