Q: Why not make a Confluence 4.0 plugin, that will monitor "User Editor Efficiency" thusly:
Lines_created + lines_edited / time_in_editor - obvious_idle_time
The proof is in the pudding. I am intrigued by the new editor, but, I would love to see something that detects the "took 5 minutes to modify my nested table" scenarios and give us some hard data to consider vs. "the noobs are SO happy!" in this conversion of editors.
Make sure the plugin works with 3.5.13 too!
