Hi everyone, I'm the developer of Calyx. I was a Ghostty user but kept running into the same problem: too many tabs, no way to organize them. Ghostty doesn't have tab groups or a plugin system, so I built Calyx using libghostty as the rendering engine. The idea is simple — keep Ghostty's speed, but add the workflow features I was missing: - Tab Groups — color-coded, collapsible groups to organize tabs by project - Co…

Hi, thanks for the feedback! To clarify, I do use the built-in .glassEffect() modifier on SwiftUI components (sidebar, tab bar, command palette, browser toolbar). The terminal surface itself is the hard part. It's backed by ghostty's Metal renderer which draws its own opaque background, so simply slapping .glassEffect() on it doesn't work. I've been working on improving transparency there but it's not as simple as a…

None of the UI elements in the screenshot follow apple liquid glass styles / guidelines afaict, whether or not glassEffect() is being used.

Fair point. I'll review the guidelines more carefully and update the styling. Thanks for pushing on this.

To be fair: no, I dislike it. It looks completely unreadable. I still don't know why Apple thinks this is a good idea.

I've updated the glass styling since then. Would appreciate it if you could take another look. https://github.com/yuuichieguchi/Calyx

A product tagline that: - name drops some technical thing, instead of saying what it does - mentions some other non feature Cool I guess?

The README has the full feature list. The tagline is just a one-liner. https://github.com/yuuichieguchi/Calyx

It would be hard to convince me to move away from iterm2. But a theme for it would get massive adoption.

Appreciate it! Calyx has more than just the looks though. Tab groups, session persistence, command palette, git sidebar. Might be worth a try. https://github.com/yuuichieguchi/Calyx
