I have set quite many inspections to show at "info" level (shown as "yellowish underwiggle" in the source).
Still the square at the top of the right gutter is yellow, even if my file contains no warnings, but just infos.
IMHO this should be changed, so that the file as a whole is indicated as "green".
The concept of inspections suffer a lot if you can't hold to the one premise
"Keep the code green"
If it's yellow anyway people won't care for one more or less warning in the code.
What do you think?
