This is great @enderahmetyurt! Awesoem work!

There's only one thing I'd like to do more.
Move the arrows to the right side and make them blend in. Make them look like the trash icon (or even smaller if they look nice).

Thanks for working on this.

Thank you for all your effort on this contribution @enderahmetyurt. It turned out great!

I fixed a bug in the drag-and-drop logic that was swapping elements instead of inserting the dragged element in the intended drop location.

Additionally, I added localization support for the reorder title and refactored the label getters.
