Similarly, without wanting to make this a thread of people repeating the same things, I’d be interested in purchasing one of these with its current features.
When I find myself short of type C ports, it is usually because I’m plugging in more low-speed, often short-term uses, things like hardware keys, transmitters for presenters, wired keyboards/mice, simple audio interfaces, etc. These don’t need more than standard 5V/1.5A, and don’t need more than 3.1gen1. Having one of these expansions would mean that those devices wouldn’t need to take up the fully-featured ports.
