BetterOneTab
A better OneTab for Chrome
Storing and grouping tabs are very useful. Onetab could help you to store the tabs you opened to free up your resources and remove clutter. But Onetab still lacks some features such as the simple list and just storing selected tabs. Since One tab it's not open source and because they update very rarely I decided to make a "Better" Onetab extension. If you used OneTab in the past, you can use Better Onetab like before. Expect to store all tabs from a window, you can also just store the tabs you selected. Better Onetab still provides the ability to store all tabs, store left or right tabs, and any others. And you can also use it from the context menu. Samely, you can also use "pin list" to keep a list that will not be removed, set the title of a list or drag to change the order of tabs. Even you can set the color of a list in the new version. You can change the "Behavior when icon is clicked" in the options page and enable or disable "simple popup list". -

Elastic APM Node.js Agent
Elastic APM Node.js Agent
This is the official Node.js application performance monitoring (APM) agent for the Elastic Observability solution. It is a Node.js package that runs with your Node.js application to automatically capture errors, tracing data, and performance metrics. APM data is sent to your Elastic Observability deployment -- hosted in Elastic's cloud or in your own on-premises deployment -- where you can monitor your application, create alerts, and quick identify root causes of service issues. First, you will need an Elastic Stack deployment. This is a deployment of APM Server (which receives APM data from the APM agent running in your application), Elasticsearch (the database that stores all APM data), and Kibana (the application that provides the interface to visualize and analyze the data). If you do not already have an Elastic deployment to use, follow this APM Quick Start guide to create a free trial on Elastic's cloud. -
