No support, because there is already such a feature. When lions run, there will be an additional box on your den showing which lions have run with the option to claim a specific lion and an option to reclaim all the lions that have left.

As for the alert notice, you get a daily rollover summary every time you do a rollover that shows up in your inbox that you are alerted about every time there is something to inform you about. You are also given all sorts of symbols on the list of lionesses that show if they are in danger of leaving due to overcrowding, low mood or starvation. The symbols are seen here: http://liodenwiki.wikidot.com/symbols.

I've been away for some time and logging in forced me to rollover even if I didnt want to yet, so no I didn't see that. All I got in messages under game notifications is "2 Lioness have left due to overcrowding" - How does a number tell me exactly which two?

On your den page, it will show which two lionesses specifically have left, and give you the notification. It does not tell you them in the message, but you will get a new section on your den page showing which lionesses have left your pride, and they give you 7 real life days from the day they run away to reclaim them.
