Whoa, I didn't expect the thumpcard "Compiler-related issue, Not our problem, read the rules" is played so early in the game. Beat me how this isn't related to C::B anyway, because the kind of compiler used in this case doesn't make sense.
Ok, allow me to reform the question to this:
Is it possible to add a whitelist/blacklist filter in the Build Messages tab?
Informational side note:
The build message tab has a File column already. But a way of sorting it's entries doesn't seem to be implemented.
