Greenhood Wallet 4+

New Functionalities
* Create additional active accounts: Now you can create extra active accounts with full transaction capabilities in addition to your main account, unlike the existing 'read-only' following accounts. Active accounts allow sending money and NFTs, not just receiving them.

* Shared accounts: Introduce shared accounts by adding another Greenhood user as a signer. This grants them the same transaction rights you have. Ideal for group financial management, like homeowners' associations.

* The Greenhood Handshake: A new protocol for easy account sharing through QR code scanning. This requires physical proximity, enhancing trust just like a real handshake.
Create signer addresses manually: Create and add signers to shared accounts manually, bypassing the need for a Greenhood Handshake. Useful for setting up accounts remotely.

Improvements:
* NFT loading consistency: Consistency in loading NFTs has been improved.

* Faster dApp list: Improved loading speed for the dApp widget.

* Improved transaction validation: Improved validation in transactions to prevent sending to the wrong blockchain.

* Loading indications: Visual indicators during app start-up to show data initialization.

* Account renewal function: Refresh your account overview with a simple pull-down gesture.

Future Note:
* Multi-signature expansion: The introduction of multi-signature will be followed soon by the ability to specify the number of required signatures for transactions. Increase security by setting multiple signers, e.g., require 2 out of 5 signatures for any transaction, ensuring collaborative approval.
