i found no botton to toggle this in pieces OS menu :0

then, i used codex and gemini cli to analyze

• E:\Runtime\Pieces\Pieces OS
• C:\Users\Xcz\AppData\Local\Mesh Intelligent Technologies, Inc\Pieces OS\com.pieces.os

to help find the potential '.json','.yaml','.yml','.toml','.ini','.conf','.config','.ps1','.xml' configure file,
and the potential snapshot-num key-value set,
0 result return.

so i came here to ask for HEL :P
