Nested albums support and import/export

Hi,

Quick question does this plugin supports nested albums? Say we have an archive with years and months, so the first page will show all yearly albums then by clicking it it will show all monthly albums inside each year.

Also when it’s mentioned you have import/export feature, will it import just all images as bulk or can it recognize the albums from say inside NextGen Gallery and create/import these from NextGen to your Gallery as albums? Do I have to create albums manually after import?

Thank you.
