I'm aware that geth can take an option to change the location, as described here: Possible to store the blockchain in a different directory?
But what about the graphical Ethereum Wallet? There doesn't seem to be a config file anywhere. (I'm on Linux.)
My home directory is a flash drive and I have a larger disk drive for bulk storage, so changing would be nice.
If there's also a way to change the place keys are stored, that'd be cool too, since secure delete works better on disks than on flash.
