Last Sketch on Startup

Most relevant area for this enhancement?

Core/Environment/Rendering

Feature to enhance

IDE startup behavior (Base class logic)

Desired enhancement

Automatically restore and open the last sketch the user worked on when the IDE starts, if no sketches are passed via command line.

Potential benefits

Saves time by eliminating manual reopening of recent sketches

Improves continuity and workflow when restarting the IDE

Matches behavior users expect from modern IDEs/editors

Easy fallback to default handleNew() behavior if the last sketch is missing

Possible drawbacks

No response

Additional context

Users may not expect sketches to reopen automatically if they prefer a clean start

If the last sketch folder was deleted or moved, the IDE will fall back to a new sketch — which could cause confusion if not logged clearly

No toggle yet to disable the feature (could be added in the future)

Would you like to work on the issue?

Yes

首先定位 Core/Environment/Rendering 中 IDE 启动 Base 类的逻辑，并跟踪命令行 sketch 和默认 handleNew() 路径的处理方式。定义上一个 sketch 的查找逻辑以及缺少文件夹时的回退逻辑，然后验证只有在命令行未传入 sketch 时，启动过程才会恢复之前的 sketch。
