KMind v2.9.0 Reconstructs the Bottom Layer, Adds Node Hyperlinks and Theme Designer
Description: Hello everyone, after several months of refactoring, KMind 2.9.0 is ready to launch~~ We sincerely thank more than a dozen enthusiastic community members for their testing. The purpose of this refactoring is to better integrate with Siyuan, laying the foundation for future advanced features such as direct interaction between Siyuan blocks and mind maps, and MOC functionality.
New Features:
1. Added global node hyperlinks, which can be placed in any external software, such as Anki or any other external software. Clicking the hyperlink will open Siyuan and jump to the specified node in the specified mind map

2. Added theme designer & sharing functionality. After designing and saving a theme, you can use it in any KMind mind map and global configuration, and quickly share it with others or import themes shared by others~
Note: After designing and saving a theme, you need to reopen the mind map to select the newly designed theme

3. Launched a new theme sharing website
