VK Flex is a functional extension that enhances the user experience on the popular social network VKontakte. This Chrome add-on offers a range of features that make navigating VKontakte more convenient and enjoyable.

One of the standout features of VK Flex is its video downloading capability. Users can easily download videos uploaded on VKontakte, although it currently does not support downloading livestream recordings or videos embedded from platforms like YouTube or Vimeo. The extension also allows users to fix the menu in place, hide ads on the left side and in the news feed, and display the age and/or zodiac sign of other users on their profiles.

Additionally, VK Flex helps users skip the redirection page to external websites (away.php) and provides a quick link to the calendar in the left menu. When clicking on "My Videos," users are redirected directly to their video recordings. The extension also notifies users of new events through pop-up notifications, sound alerts, and a counter next to the extension icon.

Overall, VK Flex is a convenient and visually appealing add-on that enhances the VKontakte experience. It offers a range of useful features, although it is important to note that music downloading is not supported.
