1. Clan Mate notifications:
We've all been there, you're in war, and you need a troops from a certain clan mate, only problem is they're offline.
Clan Mate notifications will fix this, you can click on your clan mate's name and hit "Request assistance", then hit confirm. That clan mate will then get notified that they're need, "Leader, your clan mates need you!', in which they can respond however they like.

Players would be able to disable this, in cases of it being abused, and the notifications will that have a 30 minute cool down.

This will help eliminate 3rd party ways of communicating and help clan communities altogether

2. Builder boost:
As we all know, multiple builders on single upgrades is blacklisted, but this is something SC has claimed to be considering, so support for it would be useful.

The idea is you will be able to boost your builders for a certain amount of time, similar collectors and barracks, which will speed up how fast the upgrade gets down. (Ex. 2h boost, 4x speed, 20 gems)

This would be very useful as 1. SC gets gems more often (As more people can use it), and 2. Upgrades can get done faster, but you down have to spend a ton of gems to completely finish the upgrade.

3. End replay sharing cool down for 1 gem:
I shared the wrong replay, and I don't wanna wait 30 minutes to share the right one. ;-; ;-; ;-;
