v0.1.3

• Linux (experimental): a Linux version, following nvdweem/PCPanel's approach: the panel through hidraw (with a udev rule), audio through pactl (PulseAudio or PipeWire), the tray and settings window through GTK and WebKitGTK. Nearly everything works, including the volume popup, cheat sheet, visualizer and alerts. Tested with a PCPanel Pro on Ubuntu; see the README for setup and limits.
• Fixed: a panel label too long for its spot could freeze the settings window.
• Lights off while you're away: the panel goes dark while the PC is locked, its screens are off or it's asleep, and lights up again when you're back. On by default; turn it off in Settings.
• New apps start at their dial's level: when an app starts playing sound, it takes the level of the knob or slider it's mapped to, instead of whatever Windows remembered. On by default; turn it off in Settings.
• Report a problem (tray menu and the Log tab) opens a GitHub issue with the version, Windows version, panel and recent log already filled in. You see and edit everything before it's posted.
• SteelSeries Sonar (experimental): knobs and sliders can set a Sonar channel's level (Master, Game, Chat, Media, Aux, Mic; in streamer mode, the personal mix, the stream mix or both), and buttons can toggle its mute. Built from the API other open-source apps use and not yet tried with Sonar itself, so please report how it works.
• Safer settings server: only the settings window the app opens can read or change your settings. Each start makes a new key, so other programs on the PC can't use it.
