 - **Connection**: Experience a smooth connection/disconnection with board in single click.
 - **Real-time Visualization**: Visualize incoming data without any jitter from the board in real-time.
-- **Recording**: Record the signals data and download data in csv file.
+- ****Frame Buffer Feature**: View and save up to the last five snapshots of your data. Navigate snapshots using left/right buttons, with channel count adjustments resetting snapshots for the new configuration. Zoom in or out for a closer look!
+- **Recording**: Record data indefinitely in CSV format or set a timer to automatically stop recording.
+- **Download/Delete**: Manage recorded files efficiently with a popover menu to download or delete individual files from IndexedDB. Additionally, download all files as a ZIP or delete them in one click.
+- **Zoom**: Control your view with zoom-in and zoom-out features for both detailed and overall views.
+- **Filter**: Enhance biopotential signal quality with intuitive filter controls. Apply filters for EMG, ECG, EOG, and EEG signals using dedicated icons and the master button for all-channel application.
+- **Channel**: Plot and view multiple data channels in real-time, each color-coded for easy identification.
+- **Disconnect**: Easily terminate the connection to the development board with a simple click for a seamless disconnection process.
