Version: KDE4 Progress Viewer (using KDE Devel) Installed from: Compiled sources Perhaps it would be a good idea to queue IO actions intelligently, i.e. if copy two things to or from the same device, do them sequential instead of parralel. Example: sda: 40 mb/s hda: 20 mb/s hdb: 15 mb/s Now two copy actions on sda should probably rather be executed after another, while it'd be fine to have transfers between sda-hda and sda-hdb simultaniously. (Maybe in ksyscoca benchmark results could be safed for that *g) I hope you get the idea, this is more valid even if you drag multiple things onto your mp3 player and it's trying to copy everything at once and when you decide to just unplug it and run for the bus/train and check it out nothing is completed...
Not sure this is still relevant in KF5.
