It's a real native terminal, not an Electron skin, and the Skin Builder actually works - I dropped in a random photo and had a usable themed terminal in under a minute. The agent alerts (dock bounce when Claude Code or Codex is actually waiting on you) are what keeps it open all day for me, more than the visual skins.

Thanks Omri — genuinely useful review. On the preview: that’s actually in there now. The Skin Builder has a Preview button that floats a live-updating preview while you edit, and “Use Now” swaps the skin straight onto your running session — skins load live, no restart — so you can see it with real output and flip back if it reads wrong. Linux is the honest no: it’s AppKit + SwiftTerm all the way down (the whole reason it isn’t Electron), so Linux would be a rewrite, not a port. And you’re the third person this week to say the alerts are what keeps it open all day — the copy is catching up to you all.
