Suggestion: add Sync using github account

Hi !

It would be nice to have our preferences and sessions saved and synced automatically between platforms. I have a PC and a Mac and it would be awesome to have both of them in sync.

Maybe using our Github account would be a good way, without having to have your own server/account infrastructure. Like the way VSCode Sync Settings works :)

Keep up the good work! This software is awesome

The issue names no files, tests, or entry points; begin by clarifying the account, storage, and session-sync scope. Done should be defined as an agreed GitHub-based cross-platform sync design with acceptance criteria and tests identified.
