Currently, I have to configure all clients one by one with the same settings whenever I have new devices, and since data.json include passwords related data, it won’t be a wise choose to treat it as a backup-able config file which can be used to copy/paste to restore the client common config, like when to wipe the copied passwords.
And for the browser plugin, there is non-existing feature to export/import the common settings.
Not like other client, password data file is just password data file, client settings config file is just client settings config file, it is really inconvenience for users to set the client over and over again.
