nopTools has released Shipping Director 1.02. It is available for both NopCommerce 2.3 and 2.4.
You can download it from the Download Trial link on its product page on www.noptools.com.
1) Relaxed license check allows www.mydomain.com as well as mydomain.com.
2) Automatic Update capability. If you have a prior version installed, it will detect it and upgrade settings, locale strings, etc. To install, overwrite the files in the plugin folder with what's in the downloaded .zip file.
3) Packing - "Exclude Item Expression". You can suppress items from being packed. (E.g. can handle complex free shipping scenarios - unpacked items do not contribute to package weight or dimensions)
4) $PackageCount variable. Set after packing with the total # of packages packed. If you are using packing, then you should check this after the Packing type, so that you can indicate "Free Shipping" if all items got excluded.
5) $ShippingOptionsCount variable. Set after using an external shipping plugin with the total # of shipping rate options it returned. Not typically used, but If you are doing something where you think no options will match, then you should check it and say something like "call for rate".
