List of altcoins available for a switch mining should be editable by user. Say i don't want to mine ASC or PPC even thou it is most profitable right now.
Making a custom list of favorite coins to mine would be the best option for me.
Ok. Can you share why you don't want to mine some specific coins? Are they "political" reasons, or because you personally don't think they are profitable. Or do you have some coins that your miners do poorly on, and if so, why do you think that is?
Sure. My experience with one of the multi mining pools i used to mine on SHA256. Pool calculates current most profitable coin and switch all users to mine the coin. But at some point the most profitable coin is bitcoin, which is impossible to find a block with a current number of miners. Or PPC coin, which has quite big difficulty and very low chance finding a block. I don't see any reason to spend 30 minutes digging bitcoin or PPC with no chance to find a single block, instead of doing DEM or UNO meanwhile.
