zcash-qt-wallet v0.2.0 is now fully sapling ready. Create sapling addresses, send to and from sapling addresses all from the UI.
Head over to the downloads page (https://github.com/adityapk00/zcash-qt-wallet/releases) to test it out.
Note: Sapling is currently actively only on testnet, so you can try it out against testnet. Once it activates on mainnet, it will automatically appear in the UI.
