I wonder whether you can set the image at startup wallet with a transparent background. All wallets one and the same problem. At launch, logo coin square white background. Not to be a downer, I just think it would be much prettier logo with a transparent background. Forgive me for my perfectionism))) Thanks to developer for his work! Now I'm even stronger hold coins!)

What is coin control?
When you send bitcoins to someone else, the bitcoin client chooses kinda randomly which of your addresses will send the coins. With coin control you can exactly choose, which of your addresses will be the sending addresses. And even more specific which of your unspent outputs will be the sending inputs.
  
What is an unspent output?
Lets say your bitcoin address is 111. Now someone sends 1 BTC to this address. Now address 111 has one unspent output. Now someone else sends 2 BTC to this address. Now address 111 has two unspent outputs and a balance of 3 BTC in total. Now lets say you want to send someone 0.1 BTC. One could say "ok, simply subtract 0.1 BTC from the first unspent output and send it". But this is not possible, because the bitcoin protocol works different. You always have to spent the whole output. This means in this case the bitcoin client would take the first unspent output, send 0.1 BTC to the other person and 0.9 BTC back to yourself. For this the client creates a new change address in the background and adds this address to your wallet. This address would then have one unspent output of 0.9 BTC. This means every wallet has kinda "hidden" change addresses. For example if you now would loose your wallet, but still know the private key of 111, you would be only able to get the 2 BTC back. The 0.9 BTC from the change address are gone, because you would have to know the private key of the change address.
  
Why coin control?
The first version of coin control was called "Patching The Bitcoin Client To Make It More Anonymous". Sometimes when you receive bitcoins, the sender or even the public knows that it is you who owns the bitcoin address. Now if you later want to make a real anonymous payment, you shouldnt use those coins. Also you get full control over your unspent outputs and can do things like choosing which address actually owns the coins, clean them up or send all change back to the origin address etc. You can also prevent the bitcoin client from creating a change address by exactly sending the amount of selected unspent outputs minus the fee. Also you get a better impression of whats going on in your wallet and get a better understanding of the bitcoin protocol.

Main

    Settings checkbox "Display coin control features (experts only!)" (default=no)


Tab Send coins

    Button Inputs
        click on this button opens actual coin control dialog. If no Inputs are selected "automatically selected" is shown.
    Change Checkbox
        checked -> provide custom change address


Coin Control Dialog

    Shows a list of all unspent outputs with two view modes
        tree mode: outputs including change are grouped by wallet address
        tree can be opened showing the actual outputs for this wallet address including change
        if change, the change bitcoin address is shown in column "address", otherwise the column "address" is empty, because its a direct output of the wallet address having the bitcoin address already shown in the parent node (same with label)
        list mode: simple list of all unspent outputs
    select outputs by checkbox -> only the checked outputs are used when sending a transaction
    if none are selected -> coin control inactive (just as normal)
    check/uncheck all by clicking on "(Un)select all"
    sort colums
    tooltip available in column list mode in column label for the change (shows from which address the change came from)
    Context menu
    Copy to clipboard (amount,label,address,transaction id,lock,unlock)
    Labels at the top
    Quantity: number of selected outputs
    Amount: sum of selected unspent outputs
    Fee:   see "Calculation of fee and transaction size" below
    minus fee: simply the amount shown is "Selected" minus the amount shown in "Fee"
    Bytes: see "Calculation of fee and transaction size" below
    Priority: priority = coinage / transactionsize. coinage = value * confirmations.  miners order transactions by priority when selecting which go into a block
    Low Output: "yes" if any recipient receives an amount < 0.01BTC
    Change: shows the change you get back
    direct right click the labels for copy amount to clipboard

  


Selection
In this version of coin control, all selected outputs are going into the transaction for sure!!
Of course, if you select more than you actually send, the bitcoin core will send the rest back to you as change, just as normal.
And of course, if you select less than you send you will get "The amount exceeds your balance".
And as already mentioned, if none are selected, coin control is inactive, this means everything is just the same as without coin control.
  
Fee
If the sum of selected outputs minus the amount you are going to send is smaller than the required fee, you will probably get
"The total exceeds your balance when the transaction fee is included"
This is because you didnt select enough outputs to pay the fee.
You always must select enough outputs, so that those outputs can pay the fee.
  
Calculation of fee and transaction size
The fee is calculated according to the fee set in the Settings menu.
The calculation assumes 2 outputs in total. One for the destination address and one for the change.
The formula is nBytesOutputs + (2 * 34) + 10. nBytesOutputs is the sum of selected outputs, 148 or 180 bytes per output, depending if compressed public key.
Due to the inner workings of bitcoin the size per output is actually +/- 1 byte. Meaning the shown calculation is not always 100% correct.
If you send exactly "selected minus fee" then you will not have change (1 output only). The transaction will then be 34 bytes smaller as what was calculated before.

Free Transactions
In order to be able to send a free transaction, you need to follow the rules:
     - transaction size must be < 10000 bytes
     - priority must be at least "medium"
     - any recipient must receive at least 0.01BTC
     - change must be either zero or at least 0.01BTC
  If you violate one rule you will see a min-fee and also the labels turn red:
  Bytes.Priority,Low Output,Change. Depending which rule you violated.
  Those 4 labels also have tool tips explaining this.
  Also remember that violating one of the first 2 rules means 0.0005 PER kilobyte min-fee,
  while violating one of the last 2 means 0.0005 min-fee only.

I think there should be everything you want to know!

seems it has the same version number v1.0.0.0. Is that correct? 

how coin control works ?

Great work dev, this coin is evolving nicely, coin control now, messaging soon, marketplace, android app... Thrilled about the future

Will definitely help spread the word about the new wallet 

New wallet looks awesome! 

I wait for it till it arrives at the http://www.cinnicoin.com site. Look forward to it 

Awesome!  Great new feature for a great coin!

post it on the cinniteam twitter so the twitter community can get the new wallet, Great job, downloading
