Hi,
as I haven't found results for both terms I like to add this as a suggestion.
Hotkey I think it would be very usefull to add the possibility of setting these, especially for the functions "Start & Stop Downloading of all Torrents in the List".
TrackerImport Furthermore an option in the settings, where we can set up a personal favourite tracker list, which items automatically add themselves to the already existing/predefined tracker list of each torrent, should be very productive.
