PREVIEWING,multiple selection and a thought
 

-THe most useful feature would be the previewing/running the file while downloading(at least the first segment)
-the possibility of multiple selection of files from the transfer window for multi-pausing/resuming
-malually defining the number of downloads

and one thought about the upload limit:
i'm afraid that by combining the upload with the download limitations(by explaining that a low max upload speed will limit the download speed) you are doing the opposite of what you intented : you are "pushing" the user to become a freeloader!
If i can't have a descent downoad because my bandwith is struggling by a speedy upload, the next logical step for me is not to share much (or not at all) in order to avoid it.

Good point on the uploading thing. The download limit and the upload limit should not be linked in any way.

just noted:
 

in my "observations" thread in user experience I noted that "The number segments XoloX will attempt to download at once is equal to two times the 'upload speed' setting. Downloads have no speed limits, but I don't have the bandwidth or files to share to observe how uploads work." and ask "Does each upload get 'upload speed' K/s, or does each upload get ('upload speed' / number of uploads) K/s?"

Anyone know the answer to the question?
