Hey there, welcome to the server and I'm glad to see you're thinking along to improve the gaming experience.
As for the things you suggested.
1: If you type /bm in-game you will enable to use your skillbars with your letter keys. This way you can have multiple skillbars used at once, I believe this is what you're looking for :)
2: Giving tokens to voters would be abuse-able. Tokens are tradeable in-game. People would be able to vote with multiple accounts and trade all tokens to one account. Also giving tokens for voting would greatly decrease the donations the server receives. To continue giving incentive to vote, even to older players, new voting items should be introduced.
3: You can basically do this in every town I believe :O.
4. What do you mean with that?
