InkHUD is a special firmware made for devices like the ThinkNode M1 that have E-ink displays. It provides a number of customizable features that enable you to view and communicate directly on your device without needing to connect to a cell phone. Interactable with the user button using short and long presses. 

• All Messages: View a stream of messages from all channels
• DMs: View a stream of direct messages
• Channel Messages: View a stream of messages from a specific channel
• Positions: A rudimentary "map" showing relative position and distance of detected nodes
• Heard: A list of all nodes detected on the mesh
• Send: Send pings and canned messages. Atlavox enables this optional module by default on all ThinkNode M1s that ship, and loads the following canned messages that can be selected and sent over the mesh to any channel: OK|On my way|HELP|Hold position|All clear|Check in|Emergency|ETA 5m|ETA 15m|Delayed|Stopped|Meet here|At waypoint|Moving|Quiet|Loud noise|Trail blocked|Regroup|Found sign|Target located|Lost (You can customize this canned message list via the Meshtastic app at any time)
