+description: Enhanced command-line interface in NetObserv 1.10
+tags: CLI,Monitoring,Troubleshooting

+---
+
+The NetObserv 1.10 release introduces a sleek, interactive command-line interface powered by the excellent [tview library](https://github.com/rivo/tview) and one of its extension [tvxwidgets](https://github.com/navidys/tvxwidgets).
+
+These open-source Go packages bring a rich set of UI components such as buttons, dropdowns, popups and tables, all seamlessly integrated into your terminal.

+# Key Capabilities
+
+## Table View Enhancements
+
+The flow and packet capture keeps the same abilities, showing the flow table, cycling between `displays` and `enrichments` and applying `live filters`.

+- *Customizable Columns*: Click the `Manage Columns` button to select which columns to display and tailor the table to your needs.<br><br>

+Metrics visualization takes a leap forward with real-time graphs rendered directly in the CLI.
