The problems of stability can be solved. Stay connected only to 4-8 hosts, limit the number of hosts visible to 500 (actually this is not necessary for me, but it consumes CPU resources), and refresh your hosts list every time you see a delay in respose. BTW, older versions can be found here, and also a new one, v 1.2.0 beta and 1.1.0 beta. You need to have v 1.0.5 installed to get them to work.
