the console (the one you pull up with the ` by default) should have all of the messages in it, including messages that are sent to the main tab as well as the mission tab. If there's some reason not to do that then there should be another console for the mission tab allowing you to see a larger number of messages at once while flying (as well as allowing you to scroll up using pgup/pgdown).

I disagree with the first part and agree with the second part of your post, Eldrad.
I think general communications and Mission communications should remain seperate.

Relayer they would still be seperate. The Chat tab and Mission tab would still remain as they currently are.
The console would just have all messages.

You can see them while in space by pressing n. The mission tab in the navbox has scrolly buttons.

I just wish warnings about attacking Serco pilots would appear in the main tab. While it's OK today, when missions actually say something important to you on the fly, it's not good to have to flick over and check every time some subspace beacon gets an inferiority complex and decides to remind me not to attack my allies.

Why are you attacking your allies?

yeah, where different messages is kinda messed up right now.
