Hello 
It’s been a while before I installed the official version 5.9, but I see that the highlight option works completely differently than in version 5.8. In the previous version, this module worked much better. I used it for a quick dodge and burn and it worked brilliantly. Now it seems like it’s broken. The highlight option works the same as the shadow option. There is much less control over the whole process. Do you also have a problem with it?
