 - Store complete IP:Port instead of server IDs
 - Make Battlemetrics API key optional: this is only used for the 'Connect by ID' and 'Add server by ID' methods and is not required. If you prefer, you can simply connect/add by IP.
 - Prevent the application from launching in Game Mode on Steam Deck: Steam Deck's kiosk mode has problems sending keyboard input to third party applications. To prevent unintended usage, DZGUI now warns the user to launch the app in Desktop Mode if they attempt to use it from Game Mode. Adding DZGUI as a Non-Steam Game does work on desktop PCs, but is not recommended due to the way Steam handles subshells. For best results, launch DZGUI directly via the script/applications menu (PC) or via the desktop icon (Steam Deck).

+## Design philosophy

+DZGUI follows a specific set of guidelines, enumerated below:
+
+- Provide a free and open-source tool under GPL
+- Do not use undocumented, third-party servers to aggregate data; no central "DZGUI" server
+- All connections go to Steam and DayZ servers directly; the tool should function in perpetuity without intermediary endpoints
+- Target Linux desktop and Steam deck specifically; not a cross-platform tool
