Thanks for sharing this info! The stuff I dislike about these wallets is the amount of storage needed.
Swing wallet (ZENCash Desktop GUI Wallet on Windows): "On first run (only) the wallet will download the cryptographic keys (900MB or so)"
Eleos wallet: " First time installations may take awhile to load since ~1GB of cryptographic data must be downloaded first."
I assume we cannot delete the cryptographic keys after install. Given that, it is a lot of data being stored.
