OLWLG Advanced is a free Chrome add-on developed by charles.boyung that aims to enhance the user experience of the OLWLG tool on BoardGameGeek (BGG). This add-on makes it easier for users to navigate and interact with the OLWLG tool by adding a right-click context menu in Step 4.

With the right-click context menu, users can now conveniently select multiple checkboxes at once, saving them from the hassle of manually clicking each checkbox. This feature replaces the previous code that added arrow buttons to each cell, which was resource-intensive and slowed down the process.

In addition, the recent update (v0.3) of OLWLG Advanced introduces the ability to deselect checkboxes through the right-click context menu. This further enhances the usability of the tool, providing users with more flexibility and control.

However, it should be noted that there were some issues with the add-on when recent changes were made to Chrome Extensions (v0.4). These issues have been fixed, ensuring that OLWLG Advanced continues to function smoothly.

Overall, OLWLG Advanced is a valuable add-on for BGG users who frequently utilize the OLWLG tool. Its right-click context menu and checkbox selection features streamline the process, making it more efficient and user-friendly.
