• Persistent unread-message alerts - Added System -> Persistent alerts with OFF, 1 min, 5 min, and 10 min retry intervals. When enabled, the tracker repeats the message chirp while unread direct or non-muted channel messages remain; reminders stop when messages are read or the phone reconnects. The selected interval respects Sound: OFF.
• Per-channel notification modes - Channel actions now cycle All messages, Mentions only, and None.
• White/Black keyboard fix - OLED keyboard and T9 layouts now use the compact OLED geometry in both color themes.
