Thank you for such a meaningful extension @SignorMercurio!
In any case, it would be great if the code to preserve stickyness of the right sidebar could target the <div> where the Forum Widget extension encapsulates the whole set of widgets that are placed on the right side. This is a very suitable place for other widgets in addition to Hot Discussions so it is quite likely that other users, like me, have extra stuff there. As an example, in my case, I use:
Keeping stickyness only for the Hot Discussions extension, creates the weird overlap below:
Now, I cannot use your extension due to this fact, and it is quite likely that other users face the same limitation. It would be great if it could be easily adapted.
