Brenden, I looked into creating a page type and using a repeater to display the stored tree info, but I am not sure (yet) how that would work in the scenario where I am trying to have a word and phrase dictionary where I'm inserting them into various title and content areas.
The content blocks would work because I could create the content blocks by inserting macros to localized resources. Then the content blocks are usable by editors as they don't need to manage the macros in them, but can still utilize the reference to a centrally managed resource string. Again, I still need to actually dive into this to see if it will ultimately work, but so far it does seem like a solution.
In regards to future updates to Kentico-- are you saying that this package would not be retained?
