Since the Qt6 changes dolphin file rename is awful when renaming multiple files. When you rename a file it is displayed with the new name in new sorted order immediately. When you thus need to rename more than one file you have to scroll back to the old position. That takes a lot of time for larger file lists. It was the same in very old versions of dolphin/konqueror. In later version there was a short delay before the resorting, so you could press button down or button up to select an adjacent file and thus prevent jumping in the display. The renamed file moves to the new position, but the scroll view remains in place.

Please bring that short delay back.
