I really like it for some things but not others
A little difficult to memorize the operation of zoom,… but great lighting and clarity. Light has easy brightness slider and looking at first from download appears straightforward to operate. Yet understanding the Zoom Slider on my first project has been mental. If correct configuration of features is not found quickly I would lose the subject matter at higher zoom levels as the slider would not move magnification even though it appears it is. But, it’s free, so try it out. I’m keeping it.
