HazeOver is an interestingly useful utility. I'm big on UI and color coding. HazeOver is obviously helpful in the UI department. IMO, it works best at lower settings, 33% or so. I didn't realize that I needed its abilities until i started using it. Now I don’t want to work without it.I give a lot of presentations using Zoom and on social media platforms. Anything that helps the viewer focus without my intervention and without being too "loud" helps me out a lot! Oddly, it works with the color picker, but opacity does not affect the setting. Maybe that's logical, not sure. Suggestion:The only feature that I can suggest is the ability to affect apps that use consolidated windows. Most DAWs such as, Digital Performer, Cubase and Logic Pro, use consolidated windows. When focusing on a cell (a highlighted window within a window), it would be kinda cool if HazeOver could darken the other non-highlighted cells within the app. This would be especially helpful when giving presentations. I wouldn’t have to draw imaginary circles with my mouse to get people’s attention. Overall, zero complaints. I really enjoy interesting and useful MacOS utilities, and HazeOver is quite useful and fun to use at the same time. It takes me back to the old days of System 7 and the fun utilities that were available back then.About the price. People, don't be cheap! A good utility is always worth the price, (unless it’s a subscription). So, pay for it and enjoy!
