Correct. The string representation of DMR is different from CLI syntax.

Not that I'm aware of and I'd be surprised if such a thing exists in any 
reasonably complete form. The standard use case goes the other direction.

For example, after the user saves a property, a "Save successful" message appears. I believe this is clickable to show details, and we could display the CLI commands to rerun the action within that dialog.

I'll defer to Heiko Braun on UI details. :) My only comment is this 
needs to be unobtrusive since it's extraneous to the core task users are 
trying to accomplish. What you describe sound unobtrusive.

One thing to keep in mind with this is raw DMR operations can be 
converted readily enough into CLI low-level command syntax. But CLI low 
level commands may not be the recommended approach for achieving many 
tasks. The CLI now has quite a number of high level commands (e.g. 
"deploy") that are more user friendly. I wouldn't support any attempt to 
map console-generated operations to those high level commands, as that 
would be a likely bug nest and a maintenance nightmare.

The one exception to this is the DMR "composite" operation[1] should be 
converted to the CLI "batch" and "run-batch" high level commands, with 
each step in the composite being a low-level command after "batch" and 
before "run-batch".
