[Unreleased]

Application icon redrawn: an isometric container cube inside an orbit, replacing the three stacked blocks — the old mark read as a generic grid at panel size

Ports tab: dev servers listening on the host (ss -tulpn), sorted by port with IPv4/IPv6 rows merged, showing the owning process and PID
Free a port from the popup: kill -TERM, or -KILL via Force, behind a confirmation row
Tab-scoped clean on Ports: the broom signals every listed entry at once, deduplicated by process group
Kill targets the listener's process group (kill -TERM -- -<pgid>, group read from ps), falling back to the bare PID when unknown: a supervisor (turbo, concurrently, tsx --watch) otherwise respawns the killed child and re-grabs the port
The list covers every shape a dev server takes: this user's TCP listeners, the UDP sockets of those same processes (livekit-server --dev and other media/QUIC servers bind both), and root-owned TCP above port 1024 (a sudo-started server, shown read-only). UDP-only chatter, system services below port 1024, and container-published ports stay out

Flatpak packaging manifest (flatpak/io.github.vaulttec_dev.CosmicContainers.json) for COSMIC Flatpak / Flathub
Host Docker access in Flatpak via flatpak-spawn --host docker
Tab-scoped clean action (broom icon) running docker container|image|volume prune, with confirmation and reclaimed-space feedback
Published ports and live CPU / RAM usage per container (docker stats --no-stream, polled only while the popup is open)

Application ID renamed to io.github.vaulttec_dev.CosmicContainers (desktop entry, metainfo, icon paths)
Crate, binary, and command renamed from linux-pop-extension to cosmic-containers; settings from the old config directory are migrated on first load
Application icon replaced with an original design — the previous one was the Docker logo, a trademark of Docker, Inc.
Popup doubled in size (800×960) with 16 rows per page
Header refresh button replaced by the clean action; lists still auto-refresh every 5 seconds
Flatpak permissions trimmed: dropped --filesystem=/var/run/docker.sock (unused — the applet talks to the host CLI via flatpak-spawn) and both xdg-config overrides; added --socket=fallback-x11

Settings are written to $XDG_CONFIG_HOME when set; inside Flatpak $HOME/.config is a sandbox tmpfs, so the panel font size was lost on every restart
Panel button grows along the panel's major axis instead of being fixed to one icon width, and the applet surface is wrapped in autosize_window, so the running count is no longer clipped; the font is capped to the panel thickness
Volume prune passes -a: without it Docker removes only anonymous volumes and leaves unused named ones behind
Ports are also shown for stopped containers, read from their configured bindings (docker ps reports ports only while a container runs)
Settings path follows APP_ID; legacy config under ~/.config/linux-pop-extension/ is migrated on first load
