I think this is best explained by example.   Here goes:

You have the need to move a bunch of files but to or from a bunch of different locations.   Maybe, as is my case,  you're backing up files locally to an encrypted external drive.   The problem is if you start slinging files from a bunch of disparate areas, KDE runs every single copy/move instance you ask of it in parallel.   If you try to run even two copy operations to a truecrypt drive, your computer will slow to a crawl unless you have some serious monster.   And even the best consumer parts today can only handle maybe 3 or 4 simultaneous operations to a truecrypt drive.  This is where intelligent queues comes into play.   You could add a setting into ... well I would say Dolphin but I'm guessing under the hood it is really KIO doing this? ... that would auto-queue all copy/move operations to any given partition and/or limit to only x number of simultaneous operations altogether.   Ideally, it would still check to prompt quickly for (write into / overwrite / etc) issues like KDE already does on a move command.   Then you can merrily go along your way with organizing/moving/backing up a ton of files to and/or from disparate locations without having the computer slow down, since it automatically queues for you.   I haven't used Windows in some time, but it is my understanding that this is how Teracopy works in Windows.  It hooks into the File Manager and does this for you.   Ultracopier exists for Linux and more or less does this, but has zero integration with KDE.

Reproducible: Always




Running Gentoo and KDE 4.12.5.   Apologies if this feature is in .13 or .14.   Couldn't readily find anything similar searching in Bugzilla.
