One app that can automatically determine whether to use the internal ip or the DDNS, and all other apps you wish to use are just addon's to it determined by the priviledges set on the account your logging into the NAS with.
The more functions this NAS has (which is awesome) the more apps I need to use them, the more time wasted switching between file station/synodroid (soon to be DS download if it is any good)/ds audio/ds finder/ds photo/ds cam. And each one has to be tweaked manually to log in depending on where i last logged in (either DDNS or internal ip).
Perhaps I'm just spoilt with Synodroid automatically determining my connection method, but surely its not too hard to the Synology apps to do the same, and be bundled together so I don't have to constantly log out of one and into the other, just seems so unnecessary.
Edit - Just realised "Package" refers to an addon on the NAS itself, whoops, well this kinda still applies as it is the apps that interact with some of these packages.
