New life for iPad 5th gen

Apple never released the feature to extend a Mac display to my iPad. Fortunately, this software exists & it’s open source. It works perfectly. Your work is much appreciated

想充分利用旧设备，可惜不支持，ipad mini2 最多只能升级ios12，希望开发者能支持，让旧平板利用起来

Incredible with some lags and pencil support issues. 9.8/10

Incredible with some lag sometimes. I've experienced noticeable latency even on fast mode sometimes. Apple Pencil support could be more improved. It would be better if there were an option to make my hands zoom in/out rather than a mouse, because it sometimes mess up when I use my Apple Pencil. Still, this is such an amazing app, keep up the good work!
