The red color of tool window SonarLint-icon keeps taking my attention like if there was errors in the project when there is not. It is quite annoying. No other tool window is colorized but is using a gray icon. I suggest using a gray SonarLint icon as well. Or turning it red when there are errors if possible.
I suggest to merge your thread with SonarLint color icon, in order to track all use cases in a single place.
