OK, first impression!

Connection:
OK, after 2 minutes I had as stable connection to 3 Hosts!

Search:
I like to see from what client a files is, this is very nice!
No problems here!

Download:
No problem for an semi gnutella user, the first try was a hit

Monitor/Suchanfragen:
It would be nice if you could click on a file in the monitor, and a search for this word would start! Or?

Interface:
The green is a little bit TOO green, a darker colour would be better for the eyes!

I will write more later!
But its very nice, good job!
