Improve file operations background jobs queue

[Mythox]

I wish to change order, move up or down (draging elements) etc.

The actual queue is static and the order of elements is fixed. If i run a second jobs while one is running, when one ends, other run and two items is running all time ...

For example, i have a queue of big items (films or other large files) and i need to move or copy a simple file (a document or a any small file), this operation, the small file, is the last in the queue but if i run it, when end, other large file will be run in paralell with current first operation (other large file). This behavior is not understanding by me, i think the proper way is run the small operation and no more !!

Sorry for my bad english, i'm using google translator

A greeting.
