As far as I know that meta data about a layout is not available.
For what is available look at the "Design Functions".
I'd like this capability too. Please add to the "Product Ideas".
No, not possible
There are other creation dates missing - scripts, etc. Desperately needed here
Also add sort scripts by modified date.
There is, however, a third party tool called FMDiff that can be used to compare two versions of the same file and tell you what is different. That might serve the immediate need here...
Thanks for all the replies.
Will be trying FMDiff; that should address the current issue.
