[REQ] Command queuing

[Tisser]

I'm missing the feature to queue operations. I know this exists for the copy operation and it's just awesome!

But I'm missing it for other operations as well. To be more specific I'm currently missing it for the packer.
To be able to queue zip/unzip (or rar, or ...) operations would be real helpful.

Another thing is the queuing interface (window) for file transfers, it could use some more work. Like support "drag & drop", grid view, sorting, searching, etc...
