Similar effect could be achieved by possibility to manage behavior of DOWNLOAD slots. I would love to be able to dedicate (reserve) a slot for:
1. dl from a certain user
2. dl of a certain file/folder
3. dl of a certain file category [same as "file type" in search].
It would be necessary to have an option to set max. waiting time if dedicated slot is unused before it will be set back to common [undedicated] slot. [after normally finished dl it is turned back immediately].
The method of changing common slot to dedicated one could be for instance by right-click performed on downloading file. Pop-up menu would give options: "snap" to user (just trying to find shortest possible word

Some indication of a fact that the slot is dedicated would be useful [in current dl window ] - a different text color most probably.
Looking forward to hear why it is not possible to implement this

Thanks guys [coders] for your great work done here anyway !!!
