SidebarOverflow is a free Chrome add-on developed by Shivan that aims to remove distracting sidebars from StackOverflow. As a user of Stack Overflow, you may find the sidebars, especially the Meta and Hiring ones, to be annoying. This add-on solves that problem by cleaning up the interface and eliminating these distractions.

One of the main features of SidebarOverflow is its ability to remove the "Hot Network Questions" section, which can be a time-wasting temptation. Additionally, the add-on removes the Chat feature, which some users find to be useless.

While SidebarOverflow removes distracting sidebars, it still allows you to access useful information. The Related and Linked questions sections are retained, ensuring that you can still benefit from these features.

Please note that the extension might ask for additional permissions due to recent updates, as it now works on all StackExchange websites. However, the developer assures that these permissions are necessary for the extension to function properly.

Overall, SidebarOverflow is a valuable tool for Stack Overflow users who want a cleaner and more focused browsing experience. You can find the extension on the developer's GitHub page for further information and installation.
