Choose which notifications we want to see.

How about the list of notifications we can get while out of game in settings, where we can disable or enable them by simply clicking on/off, without the need of turning them all off.
For example, sometimes i'm getting really hard attacked while im offline, because im almost maxed th9 and sometimes, when i'm in silver/golden league i have A LOT OF SPAM on my notif. bar by "your village is being raided by...".

it's not so hard to make to let us decide, what we want to see.

I like this idea...i.e. quality feedback from your village rather than "noise".
