Anim Controller preview/editor in VSCode
Detailed description of your suggestion
The animation controller preview is amazingly useful, but, as a developer, I never use it because I always do something in parallel in VS Code. Given how Snowstorm is already an extension, having a similar feature for previewing animation controllers would help developers edit them and have an easier understanding of the flow of controllers, all while still in the primary development environment.
This is not within the scope of Blockbench, it's also not really a Blockbench suggestion. The way I can address this use-case in Blockbench potentially is by adding a reload option for animations and animation controllers. That way you can edit the file in VS Code, but still live-preview in Blockbench after pressing Reload.
