How to make frd do multiple simultaneous downloads?

Hi, I just started using frd, and it's quite easy to use, but there is something I do not understand....if i try to download multiple files....it just downloads the file at the top of the list, unless I do a forced download....i have my options set to a maximum of 5 simultaneous downloads, but it will not download simultaneously unless you do it manually. How do I make it download simultaneous files automatically?

Every plugin has own (internal) limitation how many simultaneous connections can be made. Eg. for (free) Rapidshare is set to 1 - everyone knows that only 1 file at once/IP is allowed.
So it's driven automatically/plugin.
