UI improvement : display error level

[LasneF]

given a faulty API

on this screen shot to far the level Error , warning , info is not visible

it could be set on top right nears the rules name , the current error level applied
would be nice to have a color , or icons coding for error

[LasneF]

dammed double checking in fact we got it

may be still putting it clearly level : info ; next to the rules would be clearer , let you do , or close
