We are working on implementing Quarkcoin.

If you have 2 wallets (that means you see 2 wallets on the left bar with the "New Wallet" button below it) you can choose which wallet you want to send the coins from. This means: Wallet A has a balance of 1 BTC, Wallet B has a balance of 2 BTC. You cannot send 2.5 BTC from any of them, because they are not connected, instead you must make 2 transaction, 1 transaction for each wallet, to withdraw a sum of 2.5 BTC.

The QT is different, you can only have 1 wallet (one wallet.dat) open at a time, this means you mix up the addresses, as you already stated.

I'd love to implement this!

We added your impressive coin to our multi coin wallet: http://mucowa.com/

As written above:

Thank you for testing, FYI: there is a new release (FTC added): http://mucowa.com/

Everyone can decompile the jar file and examine the source code. You'll find nothing suspicious.

Update 1.1.0

• Some minor bugfixes (Litecoin transactions appear faster now)
• Added Feathercoin

Your coin is supported by our multi coin wallet MuCoWa: http://mucowa.com/

Get in touch with us here: https://bitcointalk.org/index.php?topic=476411.0
Or here: http://www.reddit.com/r/MuCoWa/

Some details:
Currently supporting 7 coins: BTC, LTC, DOGE, QRK, FTC, CGA and DGC, more will be added soon.
Superfast: Superfast startup, blockchains synchronize way faster than on original clients.
Security: Your wallets (including private keys) stay on your computer, they are not transmitted to an external service or anything else!
Easy to use: Just download the installer (MS Windows) or the zip file (MS Windows/Linux/MacOS) and you are good to go!
Lightweight: The blockchains are usually below 1 mb each.
No scam possible: The software is written in Java, this means you can decompile the jar file (Google is your friend) and look at the source for yourself!

This is not lightweight (even if it's better than the original wallet's blockchain size). Just think you store 50 coins' blockchains, you'll probabaly need 100 GB for this.

Edit: Wallet is released: https://bitcointalk.org/index.php?topic=476411.0

You are correct, it is true that supported coins may get more attention than not supported ones, but it is nearly impossible to support all coins at once. We want to begin small for now, this means 4 coins: BTC, LTC, DOGE and CGA (the last one is not much used, we wanted to see if implementing it is possible because of its unique block reward system). We'll add coins in order of http://coinmarketcap.com/ or community requests on our subreddit: http://www.reddit.com/r/MuCoWa/

The reason why you would choose a multi coin wallet software is simple: Some people hold way more then 2 or 3 different coins, the original wallets are very heavy (lots of resources like connections, memory and disk space needed), but they want to use their coins' balances anytime. The solution is simple: One software to support all commonly known coins, lightweight and easy to use! We already made a client which is lightweight and easy to use, once it is released we'll focus on supporting more coins. This is the goal we want to achieve.

You can easily use http://www.wireshark.org/ to track what the software does. You'll fine nothing suspicious. Beside the fact that open source is not equatable to "safe", this is a common prejudice.

After this facts, there is another one, very important: We are not hiding behind aliases and nicknames (like many open source authors does), but a registered company. Take a look at https://coinbrother.com/

If this list of counter-arguments doesn't change your mind, you can decompile the software (takes not even 10 seconds), since it's Java we use to write this software.

Parts of it are open source, yes. Although not the entire code will be available to the public.

Release will be very soon.
