Rorohiko just released beta version of Action Recorder— an extension panel which allows recording and replaying repetitive actions and saving recordings as scripts.
However it doesn't work for me in InDesign CS6 for Windows for some reason: nothing happens when I click controls and, unlike it's shown in the demo movie, the default set and action are missing in the panel.
I'd like to know if it works for other people and in other versions of InDesign (both Mac and Windows).
