This is my first contribution to the project, so I appreciate your feedback and any suggestions for improvement. Thank you!

It doesn't work properly when multiple tabs are opened, and it doesn't work properly in a split window.
I feel that there are many pitfalls in getting the scrolling container through const $scrollingContainer = $('.scrolling-container');
However, it may be difficult to have a good method suitable for integration into the main code to accurately obtain the scrolling-container.

Additionally, it might be more appropriate for the scroll to bottom and scroll to top buttons to be displayed at the bottom right of the note, and dynamically displayed based on the note position, something like this:

But currently trilium does not seem to have an interface to display a floating button in the lower right corner. It may be implemented as a widget.
Thanks anyway for your contribution, Trilium needs community power.

Thanks for the feedback. I’ve pushed a fixed version that addresses the issues mentioned. Let me know if there are any other thoughts. Appreciate the guidance

I have developed an improved version that includes buttons for scrolling to both the top and bottom of the notes.

I welcome any feedback and guidance you may have

This looks great, thanks for putting this together!

That's looks great. However, when scrolling to the bottom using the scrollbar or mouse wheel, the scroll button doesn't change to the upward scroll icon.
The scroll button only changes when clicked, not dynamically.
I think this might be achievable by listening to the scroll event, but since listening to scroll events can be CPU-intensive, it would be better to offer this functionality as a plugin for those who need it.
