VK Online is a Chrome add-on developed by Dmitry Sorin that provides users with momentary notifications about new private messages and online status changes of friends in the VK social network. This free add-on offers a range of features to enhance your VK experience.

The add-on notifies you instantly about new messages, ensuring you never miss an important conversation. It also provides sound notifications for new inbox messages, making it easy to stay updated even when you're not actively using VK. Additionally, VK Online includes a counter for unread inbox messages, allowing you to keep track of your messages at a glance.

One of the standout features of VK Online is the inclusion of messages' text in notifications. This means you can preview the content of new messages without having to open the VK website or app. It saves you time and provides a convenient way to manage your messages.

Furthermore, VK Online allows you to stay informed about the online status of your friends. You can choose specific friends in the extension settings and receive notifications whenever their online status changes. This feature helps you stay connected with your friends and know when they're available for a chat.

An interesting aspect of VK Online is that it keeps your online status on VK.com as "offline." This can be useful if you want to browse VK without appearing online to others. It provides a level of privacy and control over your online presence.

Starting from version 2.0.1, VK Online asks for your confirmation to access your data only once after installation. This ensures your privacy and gives you peace of mind about your personal information.

Overall, VK Online is a valuable Chrome add-on for VK users who want instant notifications about new messages and online status changes. With its range of features and user-friendly interface, it enhances the VK experience and makes staying connected easier than ever.
