FileTree Improvement

The issue

There’re numbers of code sanity alert on my vscode about that code. The util and css does not align with the common pattern in Development Mode. There’re repetetitive uses of Api, which can be re-designed to merge logic into a class.

Steps to Fix:

1. Code Sanity Alerts:
2. Identify and address code sanity alerts, such as formatting or linting issues reported by VSCode.
3. Utility Functions and CSS Alignment:
4. Repetitive API Usage
5. Development Mode Alignment:
6. Ensure utility functions, CSS, and overall code structure align with expected patterns in Development Mode.

The WorkspaceSelector.ts need a comeplete rework, also better to seperate out the frontend code with backend. FileTree/Util/util.tsx need some thought.
