With [0.9.4](https://flows.nodered.org/node/@gregoriusrippenstein/node-red-contrib-introspection) I've made an important change: all nodes and message are **no longer** traced by default. Tracing only works on a selection of nodes.

Also msg tracing and sending messages to debug are two separate operations, neither by default working **all** nodes and flows.

Instead a selection of nodes must be made - upon which to act - **or** if you really want to trace and debug _everything_ there is an extra "All nodes?" checkbox that can be used to confirm that desire.

I think this will prevent accidental damage and frustration.
