Whatever is missing can be added, write a few feature requests what torrent or mule features would you want to see in Neo.
Many things that are missing in comparation to for example MorphXT are gui features, from the network side neolaoder is more advanced , it has NAT Traversal, ipv6 support and other protocol extensions like SCT etc... so here it is more compparable to the old NeoMule.
Adding GUI features is simple.
PS: please don't take any offense on this line if inquiry, i just want to make NeoLaoder better
