Is there any plans on putting coin control functionality into the wallet?

Yes. I am currently in the process implementing several changes (enhancements) in the protocol that I need for further development. Unfortunately, many of these changes require the hardfork, so I would like to release them all together to minimize the impact. The coincontrol will be included. If you need it urgently I could make a 'maintenance' release of course.

 would it be possible in coin control to somehow enable batch selecting of inputs?
if you have thousands of small blocks selecting them one by one can be a bit tedious  Wink

They announced the termination of exchange operation months ago. Even when the exchange was functional they did not response to my e-mails. However, they did read them.

I am not sure, I will merge in all CC-related changes and it's improvements I am aware of. However, I am going to implement the maximum PoS block reward: many of you are merging all their coins into a single input and running a wallet once a month or even more rare. According to the statistics I collected, presently only 1/3 of existing supply is participating in PoS generation on a regular basis. This is not good for the network security at all. At the same time I did a few optimizations to the PoS generation code to make it even less energy consuming than before (and thus faster and less CPU intensive) to compensate the need to have more than 1 input in your wallet. These optimizations are being tested presently. Also, the automatic low inputs merging policy is under reconsideration now.

Apart from other things I am going to introduce in the coming hard fork, I am seriously thinking on switching hashing function. There is a number of reasons, the most important of which is the time necessary to validate a block received from the network. First, I believe that memory-intensive algorithms like Scrypt-N are not serving their purpose anymore: there are Scrypt ASIC miners on the market, so apparently the memory is not a barrier for ASIC developers. From the other hand, although there are many different options like X11, X... I think it is an overkill for purpose to make the coin ASIC resistant. At least it makes block validation quite CPU-time expensive. After looking at spectrum of different hashing functions already implemented and adapted by different coins I picked the hashing function used by the JackpotCoin, the Jackpotcoin Hash Algorithm V2 (https://bitcointalk.org/index.php?topic=584481.0). This is a combination of a single keccak512 transformation followed by eight rounds of random selection (based on current internal state of the hashing 'engine') of groetsl512, skein512, blake512 and jh512 transforms. The plain C implementation of this algorithm is 30 times faster than SSE2-optimized version of the Scrypt, thus it is 30 times more energy efficient in terms of CPU computations on Intel platform (for the GPU I see the four times higher hashrate and two times drop of consumption at the wall compare to Scrypt on R9-290 and R9-280X, the Nvidia chipsets produce better ratio though). From the other hand, it is quite complex to be implemented in the silicon in the nearest future. Please share your thoughts on this.

The PI build is on my todo list as well, but has not very high priority. Also, the 64bit linux build utilizes 640K resident RAM. Although, ARM is 32bit, so it should consume less RAM (the pointers are two times smaller) I do not expect the memory requirements to be significantly reduced. Let's see if it is feasible.

well i spammed them with mails but anyway  Smiley, this baby needs another home to be traded against BTC. i just wrote in the vaultex thread. is there some near future goals in development we could use to sell grain to the exchanges. it doesn't have the newcomer advantage anymore unfortunatly.

Well, the absence of the direct BTC market is not good of course, but not a coin killer. As for development plans I would not reveal the complete details. What I can say is that most ideas aimed to make a network more secure and stable will be rolled out soon.

does anyone has a block index, etc they can zip or tar and give to me - I'm trying to synch and it's taking forever - even on a fast linux box

thanks in advance.

Not an urgent need but I'd appreciate it (if you do it in a maintenance release).

My opinion on switching the hashing function  ... Personally, I don't like it.  It feels like changing the rules after the game has began.  I see you have given it more thought than I have and will support the decision/direction of the coin.

As for staking, I often set the reserve balance to prevent staking while using the computer ... I would use coincontrol to roll-up the smaller transactions as not to see the really small POS. 

Thanks

Ok, I will try to find a time to make a stable build.

Yes, I have the same doubts. From one hand I see the hash change to be good for energy efficiency. From the other hand it is actually what you said. Ok, I will think a bit more about it.

Yes, the diff is rising, but I could not say that the number of nodes increased: I see 13 connections to the block explorer node three of which supposedly from swisscex.
