Possible disadvantages of LNAV

• Learning Curve
  Although LNAV is powerful, it has a steep learning curve for new users unfamiliar with its functionalities and command structure.
• Limited GUI
  LNAV's interface is entirely text-based and runs in the terminal, which might be less appealing to users who prefer graphical user interfaces.
• Performance Issues with Very Large Logs
  While LNAV performs well with moderately large logs, it may struggle with very large log files or require significant system resources to process them.
• No Built-in Alerting
  LNAV does not have built-in mechanisms for alerting on specific log events, which means additional tools or scripts are required for comprehensive monitoring solutions.
• Dependency on Terminal Features
  LNAV relies on specific terminal features and capabilities, which might not work consistently across all terminal emulators or remote environments.
• Lack of Advanced Visualization
  Compared to some other log management tools, LNAV lacks advanced visualization options such as charts and graphs, which can make data interpretation harder for some users.
