maybe it could print the message (and stash ID)?

That's a great idea. If nobody's beaten me to it in about 12 hours i'll get that added for you tonight.

Follow-up: my initial implementation, in trying to introduce minimal changes, leads to locking errors because of the requirement for fetching the stash info while "undo" support is manipulating the stash. It needs to be scrapped and reimplemented. It's miserably hot here so i'm putting that on hold for the time being but will get back to it as temperature allows.

I gave it a shot, and ended up in a similar situation as you :-( This was a bit tricky.

Confirmation is good :). What needs to happen is the comment/date need to pulled out first and saved in allocated strings, then the stash processing, then the strings freed. If you're up to that, please do it. My proverbial plate is currently overflowing so i won't get to this for a while (but agree that it's a very useful addition, even if it's only cosmetic).
