Basically the idea behind this feature would be to divide your download queue out in order to have a more neat and organised view
For example you have an RSS feed coming in which has filters linked to it, determining what exactly to put in your download queue. Not all of these filters bring in content that you want to download straight away (you may prioritise them and download at a later date or when you have some free quota)
These items can build up and clutter the queue. A nice solution would be to have the function of creating "folders" in the download queue area to simply move them into, in the example above the folder could be called "low priority" or "documentaries", whichever you decide.
Or you could simply create a folder called "Movies" and another called "Tv Eps" etc
The folders would ideally have a size indication as well which dynamically updates when items are moved in
Thank you,
