You might want to try my threaded interface:
you can subscribe to a thread and every time a new node
is added to it the thread will be displayed in the
Subscribed Threads section.
It is rather crude at the moment but I promise I will
improve it when PM offers an interface to external thread
managers.
New threads are listed in the... New Threads section, you can
subscribe to them, at which point they move to the
Subscribed Threads section. From there you can access the nodes
in the thread. If you mark the thread as read it disappears
from the list, but every time a new node is added to it
the Thread origin and the new messages are listed again.
I use it to monitor interesting threads, this way even
a month later when a node is added during a week-end,
which I might miss from the Newest Nodes list, it shows
there.
If you want to use it on a regular bases and if you have
a web server available just ask me for the code, so you
don't depend on (and overload!) my poor server here.
