How does the "Site Content" sidebar handle hundreds (if not thousands) of content pages - say all the blog posts written over several years. Is there some sort of pagination that kicks in at some point or does the list just keep on growing?
As far as I know, it just keeps growing ad infinitum. You might want to break down the blog posts into groups... I think that's why blog module has BlogTree under which you can put several BlogHolders acting as 'directories' in the site tree. Then you would put BlogEntries under the holders.
