Very great plug-in that manages to do most of your tasks extremely good.

Could however be further improved:
1) Show _your_ filenames in the queue
2) don't mess up with number of files still to download
3) define and defer another set of downloads that should run after the current one or rather on user command
4) settings: allow to enter a user-defined filename without changing the preset extension (i.e.: hide the file extension and add the original one by default)
5) if possible: add info about current download speed

Nevertheless: A great thank you to the developers!
