Here's some ideas I've put together since I started playing CoC about 4 months ago. I briefly read through the suggested already thread, apologies if I've repeated.
I've put the more in depth and harder to implement suggestions at the end.
__________________________________________________ _______________
*Troop training repeater
A repeater trigger option for barracks troop training.
*War matchmaking
More transparency for how the clan war matchmaking system works
*Email option for clan msgs
Having an option in your account to redirect clan messages to your account email address.
*War CC
Being able to remove individual troops from war cc and leader/co-leaders being able to remove war cc troops too.
*War chat
A temporary war chat channel that becomes available during wars between the two clans.
*Clan Leader chat
A chat or message/mail system that goes between leaders/elders only.
*War Win bonus
Broaden war win bonus to xp points and possibly introducing war trophy counter/rankings to clans and/or individual accounts.
*Clan member base layout suggestions
A 3rd tab in the base layout editor that contains base layout suggestions from other clan members that you have the option to use or edit further. This would mean clan members have the ability to rearrange other clan members bases and submit it to them for proposal.
*Internal clan training grounds
Basically, you can do mock attacks on fellow clan members bases for troop combo experimenting, base testing purposes and just generally getting attack experience. Would be able to be done in shield, like the single player map. No loot exchanged, like war attacks. Troops will still need to be bought and trained etc, which would be a passive limiter for this feature.
