Very simple request, not something that anyone can abuse, not that difficult.
When my spells are done, i get a notification. When my shield runs out, notification. Troops done, notification. Building done, notification etc.
Yes, that's AWESOME that the game reminds you of this, but some of us only play at night, so even when we receive a notification, we're not going to check anyway, unfortunately it's just another thing to vibrate my phone.
Would be very nice to turn off in-game notifications in the settings. (And I'm fine with it being all off / all on).
