Qget needs heaps of features, here's what I'd love to see:
Selecting which files within a torrent to download.
Move completed files to a different folder
Change the "max download rate" calculations, it's weird!. Currently if you download 4 files at a maximum of 100k/s, each download is limited to 25k/s, instead of spreading the 100k/s over the 4 files automatically depending on download speeds.
Be able to set upload and download limits to less than 10k/s ( I have 128kbit upload max so 10k/s up almost floods my connection)
Even with download/upload rates reduced to very low values, the qnap seems to flood the connection and make other connections very slow.
Pause/Resume all downloads in 1 button.
Change the priority of a file download to the top/bottom of the list in 1 action, it can take ages to move a file all the way to the top of the list, (>10 seconds per movement is slooooow.)
Maximum Download Rate values don't work for HTTP downloads.
And of course scheduling, but I hear that's already in development, awesome!
