What can I say? Not much has changed with Unison over the past three years or so. They keep rolling out new versions and the old problems still persist.

Header downloading and post searching is still gratingly sluggish, and opening groups with a high post counts usually ends in a crash.

Essentially, the entire program has the carriage in front of the horse, as it makes no difference how simple you make downloading files, if you can't get the headers to begin with. This is going to have to change if Unison is to survive.
