Persist Sheets
This module stores your opened sheets and it will reopen, resize, and re-arrange them after you reload or restart Foundry VTT.
Usage
No configuration necessary. In module settings, there's an option to disable auto-opening the sheets (if you are only interested in restoring position) and a button to reset all stored positioning data.
