The ability to automatically open the completed downloads and/or upload's window when DC++ starts up.
The ability for DC++ to automatically do a search on a file if you can't connect to any users after 15 minutes of trying.
Search on more than one file at a time, i.e. I can highlight as many files as I want then right click and search on all of them, instead of clicking each file individually.
A search 'queue', many hubs now only allow one search every 5 seconds, it would be good if you could allow only one search every 6 seconds (or however long you say in the options), so you don't have to sit there counting to up to 5 seconds 30 times over.
Thanks, I hope I will see some of these features implimented
