A "recorder" to record what you did, like macro in excel?

I think that function will be very goood for templating for projects.
There were a log, right? because Sketchup have "undo/redo" functions.
You can record, and than playback for some multi-function, can translate logs to ruby or add a button for it on toolbar, etc...
Were there a plugin can do somthing like that?
