A post came in on the forum the other day about disconnecting numbers of connections in SQL Developer that are open. This was on the Feature request application for a while and having a few hours free with snow 9 inches deep outside, I plugged it in.This feature now has 2 options. The first is on the main connections node where you can now disconnect all connections that are open.
The other option added was on folders. Now you can disconnect all the connections in a folder which if you have them organised by category or type can help speed up your maneuvers around the tool.
This will be in the next EA of SQL Developer 3.0.
