I have a ledger, which is great and dandy, but I wish there was one program either on pc or a actual hardware device that can store coins such as PPC, NMC (I know keep does but that's all I would use it for), STR, NXT, etc.  After the recent btce nightmare, I withdrew over half my funds from polo.  I would like to still trade but keep my coins for the alts off the exchanges.  I have no idea what is best though anymore..
