I'm currently working on a macOS application that allows users to save and load their working context, by which I mean sets of open applications and their internal states.
It has helped me reduce information overload, and allowed me to switch between tasks more efficiently - and I hope other people will find value in this as well.
It's an idea I've been toying with and prototyping in different forms on and off for about four years now.
I'm finally releasing an open Beta this summer/fall, as soon as I implement delta updates and the license validator.
