Hi,
Is there a way to avoid to push in background bfgminer output better then modify and compiling the source?
I had a look at source code and your comment about the hashrate improvement but I'd like to have the possibility to enable "-q" option by using it or not in the string for miner configuration (or better in the GUI as a tick

)
You can add arguments like that in the settings dialog, then click on "Advanced miner settings" and enter it in the correct text box according to the algorithm you're using.
