I'm imagining if it can be sorted automatically.

Example there are 40 thread in first page, then there are 10 moved thread moved with a post direction and 3 sticky thread.

3 sticky thread will automatically posted in the first 3, then 27 normal thread, then the 10 moved thread stay on bottom of first page. So this still give the readers to see the moved thread instead of moving it to specific new board or last page.
