+# Network Observability On Demand UI refactor
+
+Netobserv 1.10 update is bringing a rich and interactive interface to its CLI. This is based on the awesome [tview library](https://github.com/rivo/tview) and [tvxwidgets extension](https://github.com/navidys/tvxwidgets).
+
+These open source go packages implements clickable UI components such as buttons, dropdowns, popups and tables inside Flexboxes.

+# Capabilities
+
+## Table view
+
+The flow and packet capture keeps the same abilities, showing the flow table, cycling between displays and enrichment and filtering the displayed content.

+On top of this, it's now possible to pick columns from a popup by clicking on `manage columns` button for a fully customizable table.

+The live filter capability is also extended with suggestions, helping you to pick the right keys and values to filter on.

+When running a packet capture, you can now display the pcap content by clicking on a row of the table.

+On the metrics side, a whole new world is coming with the ability to display graphs directly in the terminal.

+
+You can cycle between pre-defined view or pick panels one by one in the `manage panels` popup for a custom experience.
+It is also possible to pick a time range from the dropdown to show up to last 6 hours of capture.

+While the metris are displayed in the CLI, it's still possible to check for the `NetObserv / On Demand` dashboard in OCP Console.
