1. Kademlia feature would be nice for better find result for everyone. Iplemented A hub independent more effective DHT based search engine.
2. Upload buffer (small send buffer) setting would be nice, because usually this uploads slows down download speed.
3. Segmet size should be adjustable. Some times it seems to be definetely too small, and this waiting times for next segments, slow down overal download speed.
4. Make default settings automatically restored for pushing button "default settings"
