Impossible to tell what messages are new since a previous visit
I find it very hard to read a mailman 3 list via the archives because it seems to be impossible to identify new messages.
With mailman 2 it was easy to use the date view, combined with the browser history highlighting previously visited links, but there seems to be no equivalent.
At the very least it would be nice to have a date ordered view as the threaded view causes new messages to be mixed in with all the old messages and with a long thread it can be pretty much impossible to find them, especially given the incremental loading of the thread.
