v0.9.0

Graphical system monitor

The sidebar is now a live graphical dashboard on Ghostty + tmux:

• Orbitron LED clock — pixel-exact, rendered with Kitty graphics
• Ring gauges — CPU, memory, disk, battery
• Network dials — download & upload, with the rate in the centre and the unit in the dial
• CPU temperature — live, no sudo (macOS SMC · Linux hwmon)
• Public IP in the network title — updates live when your network changes (Wi-Fi switch, VPN)

Faster & lighter

The sidebar no longer shells out to top every second — CPU is sampled natively (host_statistics via ctypes), and a single shared collector feeds every tab instead of each pane sampling on its own.

• Metric collection is ~67× faster — 585 ms → 9 ms per update
• A sidebar that used to burn over half a CPU core every second now sits near 1%
• It scales with tabs — the collector samples once, not once per pane
• Compact too: the whole graphical dashboard adds only ~0.5 MB (a factored gauge atlas, not thousands of pre-baked frames)

⇄ Reorder tabs

Move the current tab left / right:

• macOS — Cmd+Alt+, / Cmd+Alt+.
• Linux — Ctrl+Shift+, / Ctrl+Shift+.
• Anywhere — Ctrl-A < / Ctrl-A >

Configurable font size

New phoenix-term settings option PHOENIX_FONT_SIZE — auto (14 on macOS, 12 on Linux) or a fixed number.
