You do not need to use coin control but, simply add a POS address.. Then, You set the new address as the savings address. Will post thr directions for each separately.
When you go to spend coins and both address are within the same wallet you will need to use coin control to choose from the address of where you want to spend the coins from. Otherwise it will 'auto' choose some input and some of them might be from your 'Main' wallet. To do it without using coin control you will need two wallets.
That is correct - when you go to spend you would go to Send - click inputs to enter the Coin Control area.
If you put the Label as POS for the POS/Savings address - it will show in the coin control area.
You can sort by address so you don't accidentally pick form the main wallet coins.
The coin control is easy to use one you have walked thru it but initially it can be scary if you have not used it.
If anyone ever needs help with coin control or savings I would be able to help via Yahoo instant message - GoToMeeting or Skype
