Suggestion:Get the directory of the key file via environmental variables

Hi !
I synchronized the ".wind" folder through OneDrive, but every time I select the key file on OneDrive, the directory automatically changes to "~\OneDrive", causing other devices using ".wind" to not recognize it (the sync directory of OneDrive on other devices is not in the user directory). Maybe using environmental variables to retrieve the directory of the key file would be a good way.
Thank you for your efforts.

The issue concerns how WindTerm stores and reuses the selected key-file directory when the .wind folder is synchronized through OneDrive. Start by locating the key-file selection and directory persistence entry points, then verify behavior with different OneDrive locations across devices. Done means the selected key file remains discoverable when synchronized directories have different user paths.
