Plugins: waiting room

[krzema12]

See vercel/hyper#2648 first.

In general, plugins put on the Awesome Hyper list should be mature and stable. But some of them are pretty young and still deserve the community's attention. What do you think about creating a side list, like a waiting room? One could browse through the plugins, maybe find something interesting, help by contributing, and once the plugin may get to the actual "awesome" list?
