when you will find some time for "non critical" items, maybe you want to improve this small one:

When you use the MIB Browser and select a node to get a value, if you want to change node you have to quit MIB Browser and restart it.
Adding some flexibility by allowing to change all involved parameters (a.o. the IP address of the polled node) would be more user-friendly  ::)

Best regards,
