I've just noticed that: you should rename "Unlimited" into "Do not limit". It makes much more sense.

First is the ability to set the dl/ul limit by typing it. The range between 25kb/s and 50kb/s is pretty big for 3.5-5Mbit users.

Moreover, The option to offer translations is required.
"Seeing copies" option is required.
Option to set the port used is required.

Keep up the good work!
