Keep in mind that the IDEs message pan is used for the results. Additional menu items should be possible, but not deleting a message. (without a hack)

That is my report - I wasn't logged in.

There are already the following ideas:

It is far from optimal, but you can already surround your code with {$IFNDEF _FIXINSIGHT_} to hide it from FixInsight. Warning: Make sure that it stays valid code without the excluded code!

That would be a great enhancement! That requires https://github.com/RomanYankovsky/DelphiAST/issues/39 to be implemented, but I've already made a few changes.

My simplification was a bit bad and a sLineBreak exception is sufficient for the moment.

I can't repeat it either, so please close it.

I guess you're right regarding the duplicate while my report is the better one.

Toggling the main nodes "[ ] Conventions" or "[ ] Warnings" does not touch the child nodes and so this does not help, but it would be an acceptable solution.
