The Hatz chat interface loses too much vertical space to fixed UI elements before any typing happens, and the effect compounds when attachments are involved. Specific issues: -The top bar takes a fixed chunk of screen height regardless of window size. -When a chat has attachments, the attachment preview area can take up roughly a third of the visible screen, even before I've typed a message. -Combined, this leaves a noticeably smaller reading area for actual chat content compared to other LLM platforms (ChatGPT, Claude.ai , etc.), where the chrome/header area is closer to a fifth of the screen, leaving the rest for text. -This is worse in a browser tab (no desktop app currently exists for Hatz), since browser chrome (address bar, tabs, bookmarks bar) stacks on top of Hatz's own UI overhead, compounding the cramped feeling. Net effect: reading and reviewing longer chats, especially ones with attachments, is harder than it needs to be. The ratio of "UI chrome" to "actual content" is worse than competing platforms. I think you could resolve this by moving UI elements around on the page so it is utilizing the space more efficiently, notably the sides of the screen are not used much in this platform.
