Hmm, yes, another little embedded konsole ;)

Basically, yes.

Yes, would be good to have.

This can be complicated to implement. The idea is to have "tool output format
plugins" for makeview and for appoutputview. Elsewhere you'll end checking
regexps for all supported tools every time - we do it in make output now,
it's not that fast.

(e) can be partially implemented by using redirections in commands
like make n>m.

Hmm, it sounds like konsole would be too restrivtive for anybody except me :)
Then I have only one objection against QTextEdit in application output.
It can simply be too slow, especially with cout/cerr and tool output
formatting. The good thing about konsole is that it's fast and efficiently
handle large output.
