Feature Request: show id in admin page

Really liking it. Thanks so much for your plugin.

Here is my request:
When creating a new calendar entry I have to go back and edit it again to find out what its id is.
Then I can paste the shortcode with id into my post.
I’d really like to see the id as a field in the admin panel so I can easily remember it as I move to the post page to add my shortcode. I could also refer back to get the id code for later use, in another post, without re-editing the entry…

FYI.
1. I also needed to manually set the ul style to none because my theme overrode your css. I created a child theme so it was easy. I think it would be useful to add this information to your FAQ.

2. I used your plugin on a site with old posts. I added a calendar entry from 2008. The archive list now shows all intervening years 2009..2012. Even though no events occur in those years. It would be nice if the archive only included years for which there were events. But its a minor niggle…

Thanks again ??
