The extension is great, but I'm sitting on 4.2.2 because in versions 4.3.* the recovery functionality ("Restore") is broken, as a result of which after recovery I have duplicated groups. I ask you to return the old functionality, i.e. such: "Warning! Restoring from backup will ERASE all existing settings and groups!". This is the classic recovery from backups. Or in the new functionality, please make the checkbox "ERASE all existing settings and groups".
All this functionality is already there. Update to the latest version, and in the add-on settings in the backup tab at the bottom there is also a clear button
