qued files chosen at random & not in order??

i'm a newbie here. i would like to set the download order of files in the que to a predefined order i.e. one folder at a time instead of of a random order? can this be done? i know the priority can be set but that only allows for a few folders to be set.

is there a way to minimize the hub tabs? once they are set up, they aren't needed and take up space. other functions could be maximized in place of them. thank you all for your help.
