Questions: Bdu Messages/Captain's Log

Every new message in the Captain's Log is added to the bottom of the log, which is tedious to get to. Is it possible to set this up in reverse order with new messages on top.

In regards to those red icons that pop up indicating a sighting of a ship, convoy, or task force, that sometimes have an associated Bdu Radio Contact Message in the Captain's Log, is there a way to have that message pop up in the message box as well, so that we can see it right away?

What determines when those messages are logged in the CL? They are often for sightings that are very far out of range, rather than those closer to our location, which would make more sense (to me). In addition, they are sometimes logged, but there's no alert for it, so unless we see that red icon pop up, or if we actually go into the CL, we miss it or are late in seeing it. Is there a setting for that?

And how come most of those icons pop up without an associated message attached to it? Shouldn't there be messages associated with all red icon sightings?
