+   Enable it for the languages I use.

+   Set the highlighting mode to columns so I can see (if possible)
+   where errors/warnings belong.

+
+   Try not to display the errors. A jumpy echo area makes me nervous
+   and {{{key(C-c ! l)}}} is a nicer way to look at it usually. It
+   still doesn't keep it from being displayed, only when nothing else
+   is displayed though.
