I've just downloaded version 6 today to try out. So far I'm likeing it a lot and you guys have done an amazing job for it being the first beta.
One feature I was hoping would be added would be the ability to right click in the "files" window and have options. What I'm looking for in particular would be a refresh option to refresh the window to reread what content is in the download directory. I sometimes delete items from the directories directly rather than in newsbin and as such the information stays in newsbin till I close it and reopen it. As I will often leave it open for days having a lot of files listed that don't exist gets annoying when looking through the interface.
