I have added simpleminer support.
Please add support for the built in miner (start_mining and stop_mining commands in the cli wallet).
Many people who are not serious miners and don't want to figure out how to configure a pool can still solo mine in the regular wallet and help decentralize the network if it is as ease as a checkbox to turn on and off, with free coins occasionally being dropped into their wallet if they get lucky. A very successful coin could have millions of people doing this. This was Satoshi's original vision and unfortunately got lost in bitcoin but we can bring it back here. It is a game changer.
I am working on a version which will look more like the official Bitcoin wallet, and the GUI functions could easily be expanded.
Although, I am going on holiday tomorrow till sunday, but expect it to be revealed in some weeks.
I may also post some screenshots soon 
EDIT: Here is a quick teaser of the design itself, as the program currently works with the daemon only (wallet functionality is not yet implemented). As I have already said, I'll be working on this very hard from the weekend, and further development should take less and less time because of the flexible build-up I am using. I already have the ideas of what to add in the future, and it should end up being - at least - as comfortable as Bitcoin Core in the end.
It could also easily be rewritten when it's time for using a well-built RPC API.

I will make the binaries available once the GUI supports wallet methods.
Eh... that one is windows only as well, what happened with multi platform?
