SUMMARY
***
When I copy/move files and folders to the same location that Dolphin is currently copying/moving to, Dolphin copy/move the files and folders to the same location instead of adding the same requested task to a queue, and if by mistake I copied/moved the same files/folders that Dolphin is currently copying/moving, it will lead to a lot of trouble that could be avoided if the task is queued.
***

STEPS TO REPRODUCE
1. Copy/Move files and folders from a source location to a target location.
2. Copy/Move another (or the same) files and folders from the same source location to the same target location.

OBSERVED RESULT
Dolphin will do the same operations at the same time, which might lead to unrecoverable results.

EXPECTED RESULT
It will be better if Dolphin queue the same requested tasks instead of doing multiple copying/moving operations at the same time.
