I just release a beta version of a FULL taproot wallet for Desktops, here are the specs:

The wallet support the following Bitcoin standards:
•   Brain Wallets (not recommended).
•   Wallet Import Format (WIF) for legacy individual keys.
•   Hierarchical Deterministic Wallets (BIP 32).
•   Mnemonic code for generating deterministic keys (BIP 39).
•   Multi-Account Hierarchy for Deterministic Wallets - Legacy Format of HD (BIP 44)
•   Derivation scheme for P2WPKH-nested-in-P2SH based accounts (BIP 49)
•   Derivation scheme for P2WPKH based accounts (BIP 84)
•   Segregated Witness (BIP 141), (BIP 143) and (BIP 144)
•   Bech32 segwit address implementation with error detection (BIP 163)
•   Key Derivation for Single Key P2TR Outputs (BIP 86) ~ our default mode
•   Validation of Taproot Scripts (BIP 341 and BIP 342)
•   Electrum protocol compatible
•   Multy spending paths (address and script)
•   K of N multisignature (using Huffman TapTrees)

And here a like to the wiki where you can download it and test it.

I've build some advance functionalities not seen anywhere, here are links to some docs and videos:
