It would be interesting to have a control panel for dukes only, to help regulate clan matters. You can turn them on/off or manipulate them. Here are a couple ideas for settings to have on it. Each heading will be a tab, the first Tab being rank permissions
1. Rank Permissions

= Check Box Yes/No
This is what may appear when the Duke opens this clan rank permission setting

Buy Barrack troops

Buy/Sell Builds

Create/Remove alliances
Marshal

Buy Barrack troops

Buy/Sell Builds

Lord

Invite Players

Upgrade buildings

Buy Barrack troops

Buy/Sell Builds

Kick Marshalls/Members

Promote Members

Create/Remove Alliances
(Yes you could customize it to where Lord's have no permissions, and Members have all)
2. Buildings
This can be individualized for each building, but for sakeof organization I will put it in the Duke control panel
Tower

Color

Target Lowest HP

Auto attack enemies

Only Materials and Missile Storage
(Repeat for castle, this can be customized for each tower, but I believe it works better if it is used as a whole)
Barrack
(Input) Max Troop limit

Auto Buy Troop

Color of Barrack

Ability to sell/ buy troop (Rank requirenment, ex change to only Lord's)

Target only enemies
3. Alliance Permissions

Use Gates

Ability to access clan storage on buildings

Ability to access clan craft on buildings

If ally is attacked on clan map, buildings auto Target the attacked
4. Clan Gold

Send notice to all when gold reaches (Input)

Duke can take gold from clan gold

Give (Input) clan gold each (input) to highest workload or to (input) player(s)
5. Clan Alert

Send emails when under attack

Send alerts to allied clans when under attack

Receive alerts from allied clans when they are under attack
Thoughts on this? Is just a way for dukes to control some more settings. You can debate about whether one small setting should be added or not, but as a whole judge it.
