Ability to select what to export/import

[hjk789]

This would allow you to check/uncheck check-boxes with the pages to export/import. This way if you want to import just the settings of, for example, the Security page you would just need to uncheck all pages except the Security page and confirm importing. Another example is if you want to export only your allowlist/denylist, you would just need to leave only these two pages checked and confirming export.
