Fixed sidebar display scrolling

Dear Easy Table of Contents Team,

Firstly, I would like to express my gratitude for creating such a useful table of contents plugin. It has been immensely helpful to me. However, I have encountered a minor issue recently while using it, and I was hoping you could assist me in resolving this inconvenience.

Due to the number of my headings, I have noticed that when I attempt to place the table of contents in the right sidebar and make it fixed, it exceeds the height of the sidebar, preventing it from displaying all the headings. I was wondering if it would be possible to implement a feature similar to the floating table of contents provided in your plugin. This way, when the headings exceed the height of the sidebar, users would be able to scroll and view all the headings using a scroll bar.

I believe incorporating this feature would greatly enhance the usability of the plugin and address the issue I am facing. I would greatly appreciate it if you could kindly consider implementing this functionality. Please let me know if there are any technical details or specifications you require from my end to assist with the implementation.

Thank you for your attention to this matter. I look forward to hearing from you and continuing to benefit from your excellent plugin.

Best regards,
Sliven
