Hello guys, This is the developer of Z-index - a small Mac app that keeps videos from the web on top of other native apps in a nondisturbing way, so you can watch videos while working without sacrificing productivity. Here's a demo: I'm working on this because - I'm a nerd, and... - actually, I need an app like Z-index. Usually, I watch something on YouTube while I work. Keeping a full browser window in the corner of the screen eats up a lot of screen estate and when the browser loses the focus, it's always getting behind another window so I usually miss the most interesting part of the video. Z-index solves this by keeping the video on top of other windows and also provides a so-called see-through & click-through feature to control the apps behind the video. Here's how it looks like: If you find it interesting, Z-index is now available for pre-orders with -50% discount. The planned release date is at the end of October. Feel free to ask me anything and/or give feedback!
