I've tested qbt v3.0.0rc1 for a few mins now and I am wondering if these things only happen on XP...
1. Clicking the column tabs doesn't sort the columns in the "new torrent addition dialog".
2. There is highlighting on the left panel now, but it disappears after you click on the torrent list.
3. The folder handling seems to be the same as before. The root folder still doesn't append to the save path; therefore, the "open destination folder" still opens the orginal save path(not going into the root folder like before libtorrent 0.16.0)? I also suspect this is the reason why the .unwanted folder isn't created and the unwanted files stays in the main folder.
