Chris, 3, 1 and 4 in that order. Of course you can already do number 4 by double-clicking the titlebar of the Host column. But that would be great for lazy people. 3 would be cool, but even better is to actually implement "resuming incomplete downloads". 1 is cool to look at.....

Blackbelt Jones: You can have your own local gnutella network. In previous versions of LimeWire they let you edit the conenction string. You can just run another LimeWire using port whatever, force yourself to be an ultrapeer and change the connection string in your limewire.props file to whatever you want to use. But you must remember other clients that wanna connect to you must also have that same connection string. If you edit the connection string, LimeWire shouldnt be able to make connection to the public gnutella netowork.
